Question

Which of the following describes what needs to occur to reduce force and to do the same amount of work?

The distance that the force is exerted needs to decrease.

The mass needs to be reduced.

The distance that the force is exerted needs to increase.

The mass needs to be increased.

Answer 1

The distance that the force is exerted needs to increase

Answer 2

Answer:

The distance that the force is exerted need to increase

Explanation:

Work is defined as the product of the force and distance in the direction of applied force.

                                     W = Fd    ………………. (i)

Equation (i) shows that work done can be changed by changing either force or distance. If you reduce force, you have to increase distance accordingly to keep work done constant.
