The measure of an object's speed in a certain direction is its ________.

• force

• position

• speed

• velocity

Cars, bicycles, and people are all objects that can be in motion. What is true about motion?

• an object in motion is accelerating 

• motion is the change in position of an object. 

• an object in motion has no speed but it does have velocity

• gravity and friction are responsible for all motion
