A student lifts a set of books off a table and places them in the upper shelf of a book case which is 2 meters above the table. If she applies a force of 5 newtons to lift these books, what is the work done?

Respuesta :

If a force of 5 newtons is applied to lift books 2 meters, the work done is 10 newton meters.

How work can be calculated?

The formula for calculating work is Work = Force x Distance so for calculating work we have to multiply 2 meters with 5 newtons force then we get 10 newton meters.

So we can conclude that If a force of 5 newtons is applied to lift books 2 meters, the work done is 10 newton meters.

From the calculations, the work done on the book is 10 J.

What is work?

In science, work is said to be done when the force applied moves a distance in the direction of the force.

Given that;

Force applied = 5 N

Distance covered = 2 m

It the follows that the work done is;

W = F * d

W = 5 N * 2m = 10 J
