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 degree
2. .Work is said to be done if a force is applied on the body, and the displacement of the body takes place in the direction of a force. If the angle between the force and displacement is equal to 90∘, then work done is zero in physics.

· For example- When a Coolie is carrying a load on his head on the ground level then in physics, the work done is zero, but in general perception, it is not.
