Question

Work done W, when the force F makes an angle of y degree with the direction of displacement S is​

Answer 1

Explanation:

Case-1

Here,the direction of the force acting on the block is perpendicular to the displacement.So, the work done by the force is 0.

Case-2

Here,the direction of the force acting on the block is in the direction of the displacement.So, the work done by the force will be positive.

Case-3

Here,the direction of the force acting on the block is opposite to the direction of the displacement.So, the work done by the force will be negative
