A piece of gravel is resting on a slope.Which of the following best describes how the gravitational force pulling the gravel downward will vary with the inclination of the slope?
A)Gravitational force is not affected by the slope angle.
B)Gravitational force will increase as the slope angle decreases.
C)Gravitational force will only change with the addition of water.
D)Gravitational force will decrease as the slope angle decreases.

Gravitational force is dependent on the angle of inclination of the slope. The steeper the slope, the greater the force of gravity pulling the gravel downwards. As the angle of inclination decreases, the force of gravity pulling the gravel downwards also decreases.
