select the correct answer. which force causes a wagon to speed up as it rolls down a hill? a. friction b. gravity c. mass d. normal

Answer

Brief Explanations:

Gravity is the force that pulls objects towards the center of the Earth. When a wagon rolls down a hill, gravity acts as a downward - acting force that causes it to accelerate. Friction acts against the motion, mass is a property of the wagon and not a force causing the motion, and the normal force acts perpendicular to the surface of the hill.

Answer:

B. gravity
