A: What is distance divided by time?
Q: Acceleration is the change in ______ over time.
A: What is velocity?
Q: On a position vs. time graph, a flat (horizontal) line means the object is ______.
A: What is not moving (at rest)?
Q: A vector quantity has both magnitude and ______.
A: What is direction?
Q: If you walk 5 m east and then 5 m west, what is your displacement?
A: What is 0 m?
Q: If you travel 100 m in 20 s, what is your speed?
A: What is 5 m/s?
Q: If a car speeds up from 0 m/s to 20 m/s in 10 seconds, what is the acceleration?
A: What is 2 m/s²?
Q: On a velocity vs. time graph, a flat line means the object has ______ velocity.
A: What is constant?
Q: Is speed a scalar or a vector?
A: What is scalar?
Q: If a car drives 12 km north, then 5 km south, what is the total distance traveled?
A: What is 17 km?
Q: What is the main difference between speed and velocity?
A: Velocity includes direction, speed does not.
Q: True or False: Acceleration can only happen when speeding up.
A: What is False?
Q: If the line on a position vs. time graph is slanted upward, the object is moving ______.
A: What is forward (away from the start)?
Q: Which of these is a vector? (A) Distance (B) Speed (C) Velocity (D) Time
A: What is velocity?
Q: If a car drives 12 km north, then 5 km south, what is the displacement?
A: What is 7 km north?
Q: A car moves 60 km north in 2 hours. What is its velocity?
A: What is 30 km/h north?
Q: A ball rolls from 4 m/s to 10 m/s in 3 seconds. What is its acceleration?
A: What is 2 m/s²?
Q: On a position vs. time graph, a steep line means the object is moving ______ than a less steep line.
A: What is faster?
Q: Explain why displacement is a vector but distance is not.
A: Because displacement has both magnitude and direction, while distance has only magnitude.
Q: True or False: Displacement can never be greater than distance.
A: What is True?
Q: If a runner goes 400 m around a track in 50 seconds, what is their average speed?
A: What is 8 m/s?
Q: A car slows from 30 m/s to 10 m/s in 4 seconds. What is its acceleration?
A: What is -5 m/s²?
Q: On a velocity vs. time graph, if the line is sloping downward toward zero, what is happening to the object?
A: It is slowing down (negative acceleration).
