Question

define 1 joule of work ? write an expression for the work done when the force is acting on an object in the direction of its dicplacement.​

Answer 1

Explanation:

Work is defined as scalar product of force and displacement.

The expression for the work done when a force is acting on an object in the direction of its displacement is as follows:

W = F . S

where,

F = magnitude of force

S = displacement

1 joule is defined as the the work done when a force of 1 N displaces an object at a distance of 1 m.

Answer 2

One joule of work is done on an object when a force of one Newton is applied over a distance of one meter

Work done = w

Force = F

Displacement = s

Work done is equal to the product is of the force and displacement

We = F × s
