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

1.	How is work done by a force measured when the force : (i) is in the direction of displacement.(ii) is at an angle to the direction of displacement.
Answer» (i) Work done is given by the product of the force (F) and the displacement (d) in the direction of the force i.e., Work done = F x d (ii) Work done is measured by the product of the force (F) and the component of displacement (d) in the direction of the force i.e., Work done = F x d cos θ Where θ is the angle which the displacement makes with the direction of the force.

Answer»

(i) Work done is given by the product of the force (F) and the displacement (d) in the direction of the force

i.e., Work done = F x d

(ii) Work done is measured by the product of the force (F) and the component of displacement (d) in the direction of the force

i.e., Work done = F x d cos θ

Where θ is the angle which the displacement makes with the direction of the force.
