C)eliminate the acceleration of free fall.
D)eliminate friction.

Question

Quizplus · Accepted Answer

Galileo's use of inclined planes allowed him to slow down the acceleration of free fall. By changing the angle of the inclined plane, he could reduce the steepness of the slope and therefore reduce the speed at which objects moved down it. This allowed for more accurate measurements of motion and the development of new theories about gravity and acceleration.
