Question

What is the difference between scientific concept of work and our perception of work done in day to day life?

Answer 1

1. In physics, work done will be maximum when the angle between force and displacement is equal to $0°$.
2. Work is said to be done if a force is applied to the body, and the displacement of the body takes place in the direction of a force.
3. If the angle between the force and displacement is equal to =90∘, then the work done is zero in physics.
4. For example, When a Coolie is carrying a load on his head on the ground level than in physics, the work done is zero, but in general perception, it is not.
