Question

A nonzero net force acts on a moving ball, and the ball comes to a stop. Which statement is correct about the relationship between the net force and the ball's movement?(1 point)
Responses

An increase in acceleration causes the net force to be nonzero because causation works in both directions.
An increase in acceleration causes the net force to be nonzero because causation works in both directions.

The net force causes a decrease in acceleration because without the force the ball's velocity would remain the same.

Answer 1

"The net force causes an increase in acceleration because without the force the ball's velocity would remain the same."

Explanation: By Newton's second law, a net force produces (causes) an acceleration. If the force points opposite the ball's motion, that acceleration is negative relative to the velocity and so reduces the ball's speed until it stops.
