Question

An object that is accelerating may be: (choose all that apply) (2 points)

• not moving.

• slowing down.

O traveling at a constant speed

• changing direction.

• gaining speed.

Answer 1

All of them.

Reason: acceleration means any change in velocity (magnitude or direction). So an accelerating object can be
- not moving (instantaneously zero velocity but nonzero acceleration — e.g., ball at top of its toss),
- slowing down (acceleration opposite the motion),
- traveling at a constant speed (still accelerating if direction changes — e.g., uniform circular motion),
- changing direction (velocity vector changes),
- gaining speed (acceleration in direction of motion).
