Question

select the correct answer. james gently releases a ball at the top of a slope, but does not push the ball. the ball rolls down the slope. which force caused the ball to move downhill? a. applied force b. drag force c. friction force d. gravitational force e. normal force

Explanation:

Gravitational force pulls the ball toward Earth. On a slope, its component along the slope causes the ball to roll downward. No applied force (James didn't push), drag/friction oppose motion, normal force is perpendicular to the slope. Thus, gravitational force is the cause.

Answer:

D. gravitational force
