True, only objects speeding up is acceleration

False, objects speeding up and slowing down is acceleration.

speed up

slow down

change direction

stay at a constant speed and never change direction

True, they both measure speed

False, acceleration is the rate at which velocity changes. Velocity is the speed AND direction of an object.

Velocity is the change in distance over time, while speed is the change in velocity over time.

Velocity has a direction associated with it, while speed has no specific direction
