How is the work done by a force measured when (i) force is in directio

1.	How is the work done by a force measured when (i) force is in direction of displacement, (ii) force is at an angle to the direction of displacement?
Answer» (i) When force is in direction of displacement, then work done , W = F × S (ii) When force is at an angle θ to the direction of displacement, then work done, W = F S cos^θ

How is the work done by a force measured when (i) force is in direction of displacement, (ii) force is at an angle to the direction of displacement?

Answer»

(i) When force is in direction of displacement, then work done , W = F × S

(ii) When force is at an angle θ to the direction of displacement, then work done,

W = F S cos^θ
