Q. When you apply a force to compress a steel ball, the work done gets stored as(assume there is no loss of energy):

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?

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

Q. Assertion: Work done by stretching or compressing a spring is positive.

Reason: Work done is said to be positive when force applied and displacement are in the same direction.

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.
$C a s e 2 :$ Force is making an angle of 60° with the direction of displacement.
If the displacement is 'd' meters in both the cases, then what is the relation between the work done in both the cases?
