Q. Work done is measured as a product of force and displacement the direction of force.

Q. Work done is said to be positive if the applied force and the displacement are in ............ direction.

A force of 12 N is acting on a body and the same force 12 N is acting on the same body but in a different direction. If the body moves with a displacement of $^{'} d^{'}$ metres, then what is the work done?

Same amount of force $10 N$ is acting on two bodies in two different ways.
$C a s e 1 :$ Force is acting in the direction of displacement of the body.
