What is the best definition of motion in science?

• Motion is when an object moves in a straight line.

• Motion is the change in position of an object relative to a frame of reference.

• Motion is when an object moves in any direction for a certain distance.

• Motion is the ability of an object to move fast.

What is the difference between distance and displacement?

• Distance includes direction, but displacement does not.

• Displacement is always longer than distance.

• Distance is how far an object moves, while displacement measures the shortest path from the starting point to the ending point.

• Displacement is how far an object moves, while distance is the shortest path from the starting point to the ending point.

Which of the following is an example of a frame of reference for a snowboarder going down a hill?

• The trees and ski jump next to the snowboarder

• The snowboarder’s goggles

• 350 meters

• 0 meters

• 7 meters

A scientist records that an object moved 15 meters in 5 seconds. What did the scientist measure?

• Velocity, because both distance and time are given.

• Speed, because only the distance and time are provided, not direction.

• Acceleration, because the object is moving.

• Displacement, because the scientist measured a straight-line movement.
