• force

• reference point

An original starting point is called a ____________ and it helps us know HOW the object is moving .

• reference point

• displacement point

• motion point

________ occurs due to a change in position.

• Motion

• Indirect forces

• Reference motion

• Unbalanced reference points

_____ is the total amount of length traveled.

• Distance

• Displacement

• Velocity

______ is the straight-line distance from Point A to Point B regardless of the path taken. It depends only on the initial position and the final position.

• Distance

• Displacement

• Acceleration

______ is a measure of the amount of distance an object can travel in a certain amount of time.

• Speed

• Distance

• Displacement

The scientific units for speed are

• meters per second

• inches per second

• miles per second

Describing the speed of an object often does not completely describe its motion. To accurately describe the motion, we would need to use speed AND direction, which is ________.

• velocity

• acceleration

• reference points

When velocity changes (either the speed, direction, or both) we refer to this change as ________, which is a measure of the change in velocity over a certain period of time.

• acceleration

• speed

• velocity

Jermaine runs exactly 2 laps around a 400 meter track. What is the displacement?

• 800 meters

• 400 meters East

• 0 meters

• 200 meters SW
