Which scenario describes a change in velocity? A. A skydiver that has reached terminal velocity (a constant speed) while falling.

B. A ride that spins clockwise and then counterclockwise.

C. A car traveling east at 55 km/hr.

D. A plane traveling at 800 mph at cruising altitude.

B

Explanation:

Velocity is the distance covered in a specific direction per time taken. It is a vector quantity.

When an object reaches terminal velocity, the velocity will be constant.

But a ride that spins clockwise and then counterclockwise. Will experience many changes in velocity. Since velocity is a vector quantity which has both magnitude and direction.

Change in direction is tantamount to change in velocity. Therefore, the scenario that describes a change in velocity is a  ride that spins clockwise and then counterclockwise

c) up is the direction the magnetic force is acting on the charge.
