How to use these flashcards

Work through these flashcards in short sessions. Try to answer each prompt before flipping the card, then revisit any cards you miss until the explanation feels automatic.

Flashcard 1: Which statement is correct near Earth: gravity makes objects speed up downward, or slow down downward?

Answer: Gravity makes objects speed up downward. Earth's gravity accelerates all falling objects downward.

Flashcard 2: Choose the correct claim: Two same-size balls, one metal and one rubber, are dropped together in air.

Answer: They land at nearly the same time. Similar air resistance means gravity dominates equally.

Flashcard 3: What is the key difference between gravity and air resistance on a falling object?

Answer: Gravity pulls down; air resistance pushes up. These forces act in opposite directions on falling objects.

Flashcard 4: Identify the correct cause: why does a tossed ball come back down after rising?

Answer: Gravity slows it upward, then pulls it downward. Gravity acts continuously, first opposing then aiding motion.

Flashcard 5: Which evidence best supports that gravity is always present near Earth, even indoors?

Answer: Objects fall inside buildings when released. Gravity works everywhere on Earth, not just outdoors.

Flashcard 6: What is the relationship between mass and gravity (which objects feel gravity)?

Answer: All objects with mass experience gravity. Gravity acts on everything that has mass, no exceptions.

Flashcard 7: Which direction does Earth's gravitational force act near the surface?

Answer: Toward Earth's center (downward). Gravity always points to the center of massive objects.

Flashcard 8: Identify the best evidence that gravity acts even when an object is not moving.

Answer: A resting object still has weight. Gravity acts continuously, not just during motion.

Flashcard 9: Which statement is correct: Weight changes with location or weight stays the same with location?

Answer: Weight changes with location (gravity can change). Weight depends on local gravitational strength.

Flashcard 10: What is the name of the force that pulls objects toward Earth's center?

Answer: Gravity. Earth's invisible force pulls all objects toward its center.

Flashcard 11: Identify the correct prediction: if Earth's gravity suddenly stopped, what would happen to a dropped ball?

Answer: It would not fall; it would keep moving based on its motion. Without gravity, objects would continue in their current motion.

Flashcard 12: Choose the correct claim: In a vacuum, a rock and a feather dropped together will hit when?

Answer: At the same time. Without air resistance, all objects fall equally.

Flashcard 13: Which statement is correct: mass changes on the Moon, or weight changes on the Moon?

Answer: Weight changes on the Moon. Mass stays constant, but Moon's weaker gravity reduces weight.

Flashcard 14: What evidence from everyday life shows gravity acts on objects even when you do not push them?

Answer: Dropped objects fall to the ground. This shows gravity acts constantly on all objects, not just when pushed.

Flashcard 15: Identify the force pair acting on a book falling straight down through air.

Answer: Gravity downward and air resistance upward. These opposing forces determine the net force.

Flashcard 16: What happens to an object's speed after it is dropped (ignoring air resistance)?

Answer: It increases as it falls (it accelerates). Gravity constantly pulls, causing speed to increase.

Flashcard 17: Which statement correctly compares gravity on Earth and the Moon?

Answer: Gravity is weaker on the Moon than on Earth. Moon's smaller mass creates less gravitational pull than Earth.

Flashcard 18: What is the common classroom evidence that air resistance can change how fast objects fall?

Answer: A flat paper falls slower than a crumpled paper. Shape affects air resistance, demonstrating its effect on falling.

Flashcard 19: Choose the correct conclusion: a crumpled paper and a coin are dropped together; coin lands first. What best explains this?

Answer: Air resistance affects the paper more than the coin. Different shapes experience different air resistance while falling.

Flashcard 20: Identify the stronger gravitational pull: Earth on a person or the Moon on a person (same person).

Answer: Earth on a person. Earth's mass is much greater than the Moon's.

Flashcard 21: Which evidence best shows that gravity acts on all objects near Earth?

Answer: Different objects dropped from rest fall downward. Shows gravity affects all objects equally regardless of their properties.

Flashcard 22: Which observation is evidence that gravity acts on many different materials?

Answer: Different objects fall downward when released. Shows gravity affects all materials, not just specific types.

Flashcard 23: Choose the best evidence-based claim: If air is removed, a feather and rock are dropped together.

Answer: They fall at the same rate. Without air resistance, only gravity affects falling speed.

Flashcard 24: What is the direction of Earth's gravitational force on a dropped object?

Answer: Toward Earth's center (downward). Gravity always pulls straight down to Earth's core.

Flashcard 25: What is air resistance in the context of a falling object?

Answer: A force from air that opposes motion. Friction with air molecules slows falling objects.

Flashcard 26: What is weight in terms of forces?

Answer: The gravitational force pulling an object toward Earth. Weight measures how strongly gravity pulls on an object.

Flashcard 27: Which force always acts on a falling object near Earth, even in a vacuum?

Answer: Gravity. Gravity exists everywhere, even without air.

Flashcard 28: What is the best evidence-based claim when two balls of different masses are dropped together from the same height?

Answer: They hit together if air resistance is similar. Without air resistance, all objects fall at the same rate regardless of mass.

Flashcard 29: Which force can slow a falling object by pushing upward against its motion?

Answer: Air resistance (drag). Friction with air molecules opposes falling motion.

Flashcard 30: What is weight, in terms of gravity?

Answer: The force of gravity acting on an object. Weight measures how strongly gravity pulls on an object's mass.

Flashcard 31: What is the definition of weight in terms of forces?

Answer: The gravitational force on an object. Weight measures how strongly gravity pulls on mass.

Flashcard 32: What is the definition of gravity in Earth science?

Answer: A force that pulls objects toward Earth's center. This force acts on all objects, pulling them toward Earth.

Flashcard 33: What is the direction of the gravitational force on an object near Earth's surface?

Answer: Downward, toward Earth's center. Gravity always pulls objects straight down toward Earth's core.

Flashcard 34: What is the relationship between an object's mass and the strength of its gravity?

Answer: More mass means a stronger gravitational pull. Gravitational force increases with object mass.

Flashcard 35: What is the name of the force that pulls objects toward Earth?

Answer: Gravity. A force that attracts all objects with mass toward each other.

Flashcard 36: Which option is the best evidence that gravity is always present near Earth: jump and return?

Answer: You come back down after jumping. Gravity pulls you down even after upward motion.

Flashcard 37: Identify the missing force in this explanation: "The object falls because   pulls it down."

Answer: Gravity. Only gravity can cause objects to fall downward.

Flashcard 38: What is the name of the point that gravity pulls objects toward on Earth?

Answer: Earth's center (center of mass). All points on Earth experience gravity toward this central point.

Flashcard 39: Which option best explains why a crumpled paper falls faster than a flat paper: more gravity or less air resistance?

Answer: Less air resistance. Crumpling reduces surface area exposed to air, decreasing drag.

Flashcard 40: What is the term for a push or pull that can change an object's motion?

Answer: Force. Forces cause objects to start, stop, or change direction.

Flashcard 41: Which option is evidence that gravity is a force, not a property of falling objects?

Answer: Objects accelerate downward after being released. Acceleration shows a force is acting, not just an object property.

Flashcard 42: Which statement is correct: gravity is stronger closer to Earth or stronger farther from Earth?

Answer: Gravity is stronger closer to Earth. Gravitational force decreases with distance from Earth.

Flashcard 43: What is the relationship between mass and weight on Earth?

Answer: Weight depends on mass and gravity. More mass means stronger gravitational pull, creating more weight.

Flashcard 44: Which statement is correct: Mass changes with location or mass stays the same with location?

Answer: Mass stays the same with location. Mass is the amount of matter, independent of gravity.

Flashcard 45: What is the term for a force from air that opposes motion through the air?

Answer: Air resistance (drag). Force from air molecules colliding with moving objects.

Flashcard 46: Which option is the best evidence that air resistance affects falling speed: feather vs. rock?

Answer: The feather falls more slowly in air. Light objects with large surface area experience more drag.

Flashcard 47: Which option best explains why objects do not keep moving upward after you stop pushing?

Answer: Gravity pulls downward and reduces upward speed. Gravity constantly acts downward, opposing any upward motion.

Flashcard 48: Which option best supports gravity as the cause of falling: upward pull or consistent downward acceleration?

Answer: Consistent downward acceleration. Objects always speeding up while falling proves gravity.

Flashcard 49: Which object has greater weight on Earth: a $2\,\text{kg}$ mass or a $5\,\text{kg}$ mass?

Answer: The $5\,\text{kg}$ mass. More mass means stronger gravitational pull.

Flashcard 50: What is the best evidence that Earth's gravity pulls objects downward?

Answer: Dropped objects consistently fall to the ground. Repeated observations show gravity's consistent downward pull.

Flashcard 51: What is the direction of the gravitational force on a dropped object near Earth?

Answer: Downward, toward Earth's center. Gravity always points to the center of the attracting body.

Flashcard 52: Which option is the best evidence that air resistance affects falling: same fall times or different fall times?

Answer: Different fall times for objects with different shapes. Air resistance varies with shape, affecting fall rates.

Flashcard 53: What is the net force on a falling object when gravity is greater than air resistance?

Answer: Net force is downward. Unbalanced forces cause continued acceleration.

Flashcard 54: What is the name of the force from air that can slow a falling object?

Answer: Air resistance (drag). This friction-like force opposes motion through air.

Flashcard 55: What happens to an object's speed as it falls if air resistance is small compared with gravity?

Answer: Its speed increases (it accelerates). Gravity continuously pulls down, causing constant acceleration.

Flashcard 56: Which evidence would best support the claim that stronger gravity causes greater weight?

Answer: The same object weighs less where gravity is weaker. Shows weight depends on gravitational strength, not just mass.

Flashcard 57: What observation supports the idea that gravity acts even when nothing touches the object?

Answer: A dropped object falls without being pushed or pulled by contact. Shows gravity is a non-contact force acting at a distance.

Flashcard 58: What is the evidence-based explanation for why the Moon stays near Earth instead of drifting away?

Answer: Earth's gravity pulls the Moon toward Earth. Gravity keeps the Moon in orbit around Earth.

Flashcard 59: What is the force called that pulls objects toward Earth's center and makes them fall?

Answer: Gravity. This invisible force attracts all objects with mass toward each other.

Flashcard 60: Which option is the best evidence that gravity is a non-contact force: it pulls without touching or only works by touching?

Answer: It pulls without touching. Objects fall without being pushed, proving gravity acts at a distance.

Flashcard 61: Which statement is the best claim: why does a book fall when released?

Answer: Earth's gravity pulls the book downward. Identifies gravity as the cause of the book's downward motion.

Flashcard 62: Which situation shows air resistance is small compared with gravity: coin vs. sheet of paper?

Answer: A coin falls faster than a flat sheet of paper. Dense objects overcome air resistance more easily.
