Question

all of the following statements describe acceleration except one. which statement does not describe acceleration? choose 1 answer: a how quickly an object slows down b how quickly an object changes direction c how quickly an object speeds up d how fast an object moves

Explanation:

Acceleration is the rate of change of velocity (which includes speed and direction). Option A (slowing down) is deceleration (negative acceleration), Option B (changing direction) involves acceleration (since velocity direction changes), Option C (speeding up) is positive acceleration. Option D describes speed (how fast an object moves), not acceleration.

Answer:

D. how fast an object moves
