Question

A man has been guarding a house for one hour.why it is not considered work in science

Answer 1

Explanation:

Work = Force X Displacement

Since the man is not moving so the displacement is zero

Hence, work done = 0

Answer 2

Explanation:

This is a simple tricky question from physics.

According to physics, work done is defined as the product of "force and displacement", and is measured in the direction to the displacement of the mass.

So, work done $W=F \times d$ sin a, where a is the angle between force and displacement.

In this particular case, though the guard was guarding the gate for one hour, he has not done any displacement towards any direction. So, the work done comes out as zero.
