Question

define work write an expression for work in terms of force and displacement state the SI unit of work done​

Answer 1

Answer:

Work done = Force × Displacement × cosine of angle between the direction of force & displacement. ... The SI unit of work is Joule. 1 joule of work is done by an object when a 1 Newton of force is applied on it,and it get displaced by 1 metre.

Answer 2

Answer:

Work is said to be done when the force applied on an object produces a displacement in the object in the direction of force applied.

Work = Force \times displacement (positive work)

S.I unit of work done = Joule.
