Question

10. How can an incline plane reduce the amount of force required to lift an object?
a. increase the length of the ramp
b. increase the height of the ramp
c. decrease the length of the ramp
d. All of the above​

Answer 1

A ramp like the one in the Figure below is another example of an inclined plane. Inclined planes make it easier to move objects to a higher elevation. The sloping surface of the inclined plane supports part of the weight of the object as it moves up the slope. As a result, it takes less force to move the object uphill.
