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 objects towards the center of the Earth. When a ball is on a slope, this force acts to move it downhill. Applied force is from a push or pull by an external agent which is not the case here. Drag force acts against motion in a fluid (like air resistance). Friction force opposes the relative motion between surfaces in contact. Normal force is perpendicular to the surface the object is on.

Answer:

D. gravitational force
