• Force

Multiple Select

Which of the following statements are true about acceleration?

• Acceleration is the rate of change of velocity.

• Acceleration and velocity are always in the same direction.

• Acceleration can occur when an object changes direction.

• Acceleration only happens when an object speeds up.

Open Ended

Explain how acceleration and velocity are related when an object is speeding up versus slowing down.
