How Are the Length and Height of a Ramp (Inclined Plane) Related to Mechanical Advantage?
A. A ramp that is very long has less mechanical advantage than a shorter ramp of the same height.
B. A short ramp the same height of a longer ramp takes less effort to go up, giving it a greater mechanical advantage.
C. Two ramps of the same lengths, but with different heights have identical mechanical advantages.
D. A longer ramp will have a higher mechanical advantage than a shorter ramp of the same height.

A, B and C are False
Statement D is true. if both ramps reach the same height, a longer ramp will have a smaller elevation angle with the ground, making it easier for the object to be rolled or pushed up on it -> greater mechanical advantage.
mechanical advantage of a ramp varies directly to the lenght of the ramp, but inversely to the height it reaches.
