Question

What is work done formula explain with example

Answer 1

Work done force×displacemant

Answer 2

Here your answer.

This is the displacement of an object due to force. How much work is done depends on the distance the object is moved. This makes it easy to put work into a solvable equation: work = force * distance.

Examples:

A box is dragged horizontally across a floor by a 100 N force acting parallel to the floor. What is the work done by the force in moving it through a distance of 8 m

F = 100 N

S = 8 m

Since F and S are in the same direction,

θ = 0, where θ is the angle of the force to the direction of movement.

W = F Cos θ

= 100 x 8 x Cos 0

= 800 J (Cos 0 = 1)
