Question 20

Which of these statements is true about using a ramp (inclined plane) to move a cart onto a truck?

Accepted Answer

As the length of the ramp increases, the amount of force needed decreases.

Answer

The amount of force needed to move an object changes as you move a particular item.

Answer

It is easier to move objects on a cart than it is to move them by hand.

Answer

The taller the ramp, the more force you need to move the box.
