Question

A force of 300 N is used to move a chair a distance of 2 m. How much work is done?

Answer 1

work = force × distance
= 300 N × 2 m
= 600 J

Answer 2

It depends on the angle between the force and the displacement.

Assume the angle is α

Then W = 300 * 2 * cosα = 600 cosα J

If you horizontally push the block on a flat plane, then α = 0, then W = 600 J
