Flashcard 1: What is the direction of an object’s weight force near Earth’s surface?
Answer: Toward Earth’s center. Weight is the force of gravity pulling toward Earth's center.
Flashcard 2: Identify the correct meaning of "down" in the sentence: "The rock fell down into the hole."
Answer: It moved toward Earth’s center. Falling objects move in gravity's direction.
Flashcard 3: Which direction is "down" at the North Pole: toward the ground or toward the equator?
Answer: Toward the ground (toward Earth’s center). At any location, down means toward Earth's center.
Flashcard 4: Choose the word that completes the sentence: Gravity pulls objects toward Earth’s center.
Answer: Down. Gravity's direction is always described as downward.
Flashcard 5: Identify whether "down" is best described as a compass direction (north/south) or a gravity direction.
Answer: A gravity direction. Down is determined by gravity, not compass directions.
Flashcard 6: Which direction is "down" at the equator: toward Earth’s center or toward the North Pole?
Answer: Toward Earth’s center. The equator is sideways relative to Earth's center.
Flashcard 7: Which diagram feature best shows "down" correctly: an arrow pointing to Earth’s center or to the map’s bottom edge?
Answer: An arrow pointing to Earth’s center. Scientific diagrams show down as radial to Earth.
Flashcard 8: What does the word "down" mean in science when discussing gravity on Earth?
Answer: Toward the center of Earth. Down is defined by gravity's pull, not by our everyday sense of direction.
Flashcard 9: Which force makes objects move "down" toward Earth’s center?
Answer: Gravity. This force pulls everything toward Earth's center.
Flashcard 10: What is the direction of the gravitational pull on an object standing on Earth?
Answer: Toward Earth’s center. Gravity always pulls objects toward the planet's center.
Flashcard 11: Which option best defines "down": toward the sky or toward Earth’s center?
Answer: Toward Earth’s center. Down is defined by gravity, not by the sky's position.
Flashcard 12: Identify the direction that a dropped ball begins to move immediately after release.
Answer: Toward Earth’s center. Gravity immediately pulls the ball toward Earth's center.
Flashcard 13: What does "down" mean for a person standing in Australia compared with a person in the United States?
Answer: Toward Earth’s center for both. Both experience gravity pulling toward the same central point.
Flashcard 14: Which statement is correct: "Down is the same compass direction everywhere" or "Down is toward Earth’s center"?
Answer: Down is toward Earth’s center. Down changes with location but always points to Earth's center.
Flashcard 15: Identify what "down" means if you are standing on the side of a hill.
Answer: Toward Earth’s center. Gravity pulls toward the center, not along the slope.
Flashcard 16: Which direction is "down" relative to the ground at your feet: perpendicular to the surface or parallel to it?
Answer: Perpendicular to the surface, toward Earth’s center. Down forms a 90° angle with the ground surface.
Flashcard 17: Identify the direction a plumb line points when it hangs freely.
Answer: Toward Earth’s center. Gravity aligns the weight to point straight down.
Flashcard 18: What does "down" mean for an astronaut standing on the Moon compared with on Earth?
Answer: Toward the center of the body they are on. Each celestial body has its own gravitational center.
Flashcard 19: Find the correct meaning: Is “down” toward the North Pole, toward the South Pole, or toward Earth’s center?
Answer: Toward Earth’s center. "Down" isn't tied to geographic poles but to Earth's gravitational center.
Flashcard 20: Which statement is correct: “Down points to the same place as south” or “Down points to Earth’s center.”
Answer: Down points to Earth’s center. South is a compass direction; "down" follows gravity to Earth's core.
Flashcard 21: Identify the correct idea: Does “down” depend on a map’s top and bottom, or on gravity?
Answer: It depends on gravity. Maps show north/south; gravity determines the true direction of "down."
Flashcard 22: What is the direction of “down” for two people standing on opposite sides of Earth?
Answer: Each person’s down is toward Earth’s center. Their "down" directions point in opposite ways but meet at Earth's core.
Flashcard 23: Which tool best shows the direction of “down” at a place: a compass or a plumb bob?
Answer: A plumb bob. A compass shows magnetic north; a plumb bob hangs straight down by gravity.
Flashcard 24: Identify what “down” means if you are standing on a mountain instead of a flat field.
Answer: Toward the center of Earth. Elevation doesn't change gravity's pull toward Earth's core.
Flashcard 25: What does the word “down” mean in science when talking about gravity on Earth?
Answer: Toward the center of Earth. Gravity pulls everything toward Earth's core, not just toward the ground.
Flashcard 26: What point does “down” always point toward, no matter where you stand on Earth?
Answer: The center of Earth. No matter your location on Earth, gravity pulls you toward the same central point.
Flashcard 27: Which force makes “down” point toward Earth’s center?
Answer: Gravity. This force pulls all objects toward Earth's center, defining the direction "down."
Flashcard 28: What is the direction called “up” in relation to Earth’s center?
Answer: Away from the center of Earth. "Up" is the opposite of "down," pointing outward from Earth's core.
Flashcard 29: Which option best defines “down”: toward the sky or toward Earth’s center?
Answer: Toward Earth’s center. Gravity defines "down" as the direction toward Earth's core.
Flashcard 30: Identify the correct statement: “Down is the same direction everywhere” or “Down depends on location.”
Answer: Down depends on location. "Down" changes with your position on Earth but always points to the center.
