Question

which of the following is an example of a force causing acceleration? a book sitting still on a table a car moving at a constant speed on a straight road a bicycle slowing down when the brakes are applied a ball rolling at the same speed across a flat surface

Explanation:

According to Newton's second law of motion, force causes acceleration. Acceleration is a change in velocity. A book sitting still has no acceleration. A car moving at constant speed has no acceleration (velocity change). A ball rolling at same speed has no acceleration. But a bicycle slowing down (velocity decreasing) has acceleration, caused by the braking force.

Answer:

A bicycle slowing down when the brakes are applied
