Chapter 9, Problem 4A

How many joules of work are done on an object when a force of 10 N pushes it a distance of 10 m?

To determine

The work done on an object in Joules for a given force and distance

Answer to Problem 4A

The work done on the object for the given force and distance is $100\text{ J}$

Explanation of Solution

Given:

A force of 10 N pushes an object through a distance of 10 m

Formula used:

When a force is done on an object, the distance through which it is moved is also a factor to be considered. In this case, the product of force and distance is referred to as the “work done” on the object. It can be expressed as,

  $\text{W}=Fd$

Calculation:

The force done on the object is 10 N and the distance through which the object moves is given by 10 m. The work done is therefore given by,

  $\begin{array}{c}\text{W}=10\times 10\\ =100\text{ N-m}\\ \text{=100 J}\end{array}$

Conclusion The work done on the object for a given force and distance is 100 J.
