• speed

• displacement

• reference point

If you ride your bike around the block, returning to the exact point where you started, your displacement is __ m?

• 0 ZERO

• 1 ONE

• 1500

• 50

Distance, a reference point, and a reference __ are all needed to determine the position of an object.

• object

• motion

• direction

• displacement

You are in a car going 50 km/h and another car passes you going in the opposite direction at 50 km/h. Do both cars have the same velocity?

• They do not have the same velocity because they are traveling in opposite directions

• They do have the same velocity as both cars are going 70 km/h.

Motion can be described through a change in _____.
