Question

Tom wants to put a heavy box into the back of a moving truck. He is not strong enough to lift the box into the truck, so he uses a ramp to slide it up instead.

The ramp is as an inclined plane that
A.
increases both the force needed to move the box and the distance over which the force is applied.

B.
decreases both the force needed to move the box and the distance over which the force is applied.

C.
decreases the force needed to move the box while increasing the distance over which the force is applied.

D.
increases the force needed to move the box while decreasing the distance over which the force is applied.

Answer 1

The answer is ¨decreases the force needed to move the box while increasing the distance over which the force is applied.¨

Step-by-step explanation:

Answer 2

The ramp is an inclined plane that decreases the force needed to move the box while increasing the distance over which the force is applied. (C)

That way, you get just as much WORK done, but you can use less force, because it acts through more distance.
