Question

select all options which accurately complete the statement. a skateboard that is ______ is accelerating. choose all answers that apply: a slowing down b changing direction c moving with constant velocity d remaining at rest e speeding up

Explanation:

Step1: Recall acceleration definition

Acceleration is a change in velocity. Velocity is a vector with magnitude (speed) and direction.

Step2: Analyze each option

• Option A: Slowing - down changes speed, so there is acceleration.
• Option B: Changing direction changes velocity vector, so there is acceleration.
• Option C: Constant velocity means no change in speed or direction, so no acceleration.
• Option D: Remaining at rest has zero velocity and no change, so no acceleration.
• Option E: Speeding - up changes speed, so there is acceleration.

Answer:

A. slowing down, B. changing direction, E. speeding up
