When an object experiences acceleration, its speed must be increasing. Is this true? If not, why?

• That's true.

• That's false. An object's speed increases when it experiences velocity.

• That's false. Acceleration is any change in speed, whether that's speeding up or slowing down.

• That's false. Acceleration is a myth.
