Flashcard 1: Which force pulls a person back to the ground after stepping off a low wall (ignore air resistance)?
Answer: Gravity. Earth's pull brings all jumping objects back down.
Flashcard 2: What is the name of the force that pulls objects toward Earth even when they are not touching Earth?
Answer: Gravity. This force acts at a distance without contact.
Flashcard 3: Which direction is the gravitational force on a rock held still above the ground: up or down?
Answer: Down, toward Earth. Gravity always points toward Earth's center.
Flashcard 4: Which direction does Earth’s gravity pull a dropped object: toward Earth or away from Earth?
Answer: Toward Earth. Gravity always pulls objects toward Earth's center.
Flashcard 5: What is the term for the force that keeps your feet on the ground instead of floating away?
Answer: Gravity. This constant downward pull prevents us from floating.
Flashcard 6: Identify the force that pulls a skateboarder back down after a jump (ignoring air resistance).
Answer: Gravity. Earth's pull brings all airborne objects back down.
Flashcard 7: Identify the force that causes a thrown ball to slow down going up and then fall back down.
Answer: Gravity. It opposes upward motion and accelerates downward motion.
Flashcard 8: What is the name of the force that makes a dropped book move downward to the floor?
Answer: Gravity. This downward pull causes all dropped objects to fall.
Flashcard 9: Which statement is correct: Gravity pulls objects toward Earth, or gravity pushes objects away from Earth?
Answer: Gravity pulls objects toward Earth. Gravity is always attractive, never repulsive.
Flashcard 10: Identify the force pulling rain and snow downward from clouds to the ground.
Answer: Gravity. This downward force affects all precipitation.
Flashcard 11: Which option best describes gravity: a contact force that requires touching, or a non-contact force?
Answer: A non-contact force. It acts through space without physical contact.
Flashcard 12: What is the main cause of your weight while standing on Earth?
Answer: The pull of Earth’s gravity on you. Weight is the force of gravity acting on your mass.
Flashcard 13: Which option best identifies gravity: a push away from Earth or a pull toward Earth?
Answer: A pull toward Earth. Gravity is an attractive force, never repulsive.
Flashcard 14: What is the name of the force that causes a ball to fall back down after being thrown upward?
Answer: Gravity. This downward pull overcomes the ball's upward motion.
Flashcard 15: What is the object that Earth’s gravity pulls toward Earth in this situation: an apple falling from a tree?
Answer: The apple. Gravity pulls all objects near Earth downward.
Flashcard 16: What is gravity in Earth science, as a force acting on objects near Earth?
Answer: Gravity is a force that pulls objects toward Earth. It acts on all objects near Earth, pulling them downward.
Flashcard 17: Which force is acting if a pencil slips off a desk and falls straight down to the floor?
Answer: Gravity. Objects fall straight down due to Earth's pull.
Flashcard 18: Which statement is correct: gravity pulls toward Earth or gravity pushes away from Earth?
Answer: Gravity pulls toward Earth. Gravity is always an attractive force, never repulsive.
Flashcard 19: What force pulls a rolling ball back down after it goes up a ramp and slows?
Answer: Gravity. Objects moving upward are still pulled down by this force.
Flashcard 20: What does gravity do to an object that is thrown upward after it leaves your hand?
Answer: It pulls the object back down toward Earth. Gravity acts continuously on objects in the air.
Flashcard 21: Identify the force acting downward on a stationary book resting on a table.
Answer: Gravity. It acts on all objects, even those at rest.
Flashcard 22: Which option best explains why a skydiver speeds up after jumping: gravity or friction?
Answer: Gravity. The downward pull accelerates falling objects.
Flashcard 23: Identify the force that gives objects weight on Earth.
Answer: Gravity. Weight is the force of gravity on an object's mass.
Flashcard 24: Choose the best description: gravity is strongest near Earth or far from Earth?
Answer: Strongest near Earth. The pull weakens with distance from Earth.
Flashcard 25: Identify the force that makes rain fall from clouds to the ground.
Answer: Gravity. Water droplets are pulled down by this force.
Flashcard 26: What is the name of the force that acts on all objects with mass near Earth?
Answer: Gravity. Every object with mass experiences this downward pull.
Flashcard 27: What force keeps people and objects from floating away from Earth’s surface?
Answer: Gravity. This downward pull keeps everything anchored to Earth.
Flashcard 28: Which option describes gravity: pull toward Earth, push away from Earth, or sideways force?
Answer: Pull toward Earth. Gravity always acts downward toward Earth's center.
Flashcard 29: What is the difference between a push and gravity?
Answer: Gravity is a pull toward Earth, not a push. Pushes move objects away; gravity always pulls down.
Flashcard 30: Identify the force that causes objects to fall when released.
Answer: Gravity. This downward pull causes all dropped objects to fall.
