Chapter 6, Problem 1RQ

A force sets an object in motion. When the force is multiplied by the time of its application, we call the quantity impulse, which changes the momentum of that object. What do we call the quantity $force\times distance$ ?

To determine

The term for quantity $force\times distance$

Answer to Problem 1RQ

The term for quantity $force\times distance$ is called as work.

Explanation of Solution

When an amount of force acts over a body for a certain time interval, it is known as the impulse, which can also be termed as a change in momentum. A force can make a body move. In case, when a person exerts a force on an object to move it to a certain distance, some amount of energy is consumed. The measure of energy that is transferred in moving a body to a particular distance is termed as work, and it can be represented by the expression,

$Work=Force\times Distance$

When the greater amount of force is applied in order to move the object to a longer distance, more will be the change in energy or quantity force.

Conclusion:

Therefore, the term for quantity $force\times distance$ is called as work.
