Question

How does a ramp make it easier to move a heavy object a certain distance?A by decreasing the distance the object movesB by decreasing the amount of work required to move the objectC by changing the direction in which the object movesDby decreasing the amount of force required to move the object

Answer 1

By Decreasing the amount of force required to move an object

Step-by-step explanation:

Objects, especially simple machines, make work easier. They do not decrease the amount of work done, but actually decrease the amount of force applied. The less force applied, the easier it is to do work. Simple machines and other objects that help make work easier decrease the amount of force required to move an object.

So the answer is-

A ramp makes work easier by decreasing the amount of force required to move an object

Answer 2

When lifting an object we are required to produce a force that is greater or equal than the weight of the object in order to be lifted:

When we use a ramp we have the following distribution of forces:

In the ramp, the force decomposes into two components. A component that is parallel to the ramp and a component that is perpendicular to the ramp. Now the force must be greater or equal to the parallel component of the ramp therefore, the amount of force required must be less. Therefore, the ramp makes it easier by decreasing the amount of force required to move the object.
