Joules

One joule is said to be the work done when a force of one newton acts on an object through one meter. Prescott joule is an English physicist. The unit joule was named after the physicist. The unit of energy and work done is measured in joules. Prescott joule also was a mathematician. A joule's SI unit is a square kilogram square per second squared.

The formula of work done is force x distance.

Suppose a car has dragged a distance of 15 meters and the force applied on it was 10 newtons. What is the work done on it?

- Putting it into the equation, work done = 15 x 10 = 150 joules.

Suppose a bike has dragged a distance of 16 meters and the force applied on it was 10 newtons. What is the work done on it?

- Putting it into the equation, work done = 16 x 10 = 160 joules.

Suppose a ball in motion covered a distance of 18 meters, and the force applied on it was 21 newtons. What is the work done on it?

- Putting it into the equation, work done = 15 x 10 = 378 joules.

The work done on an object is 50joules, and the distance it covers is 56 meters. What was the force applied to it?

- Putting it into the equation, F = 50/56 = 0.893 newtons

The work done on an object is 55 joules, and the distance it covers is 5 meters. What was the force applied to it?

- Putting it into the equation, F = 55/5 = 11 newtons

The work done on an object is 57 joules, and the distance it covers is 57 meters. What was the force applied to it?

- Putting it into the equation, F = 57/57 = 1 newtons
