Question

Derive the formula for the measurement of work done when a body moves in the direction of the force applied.​

Answer 1

Answer:

W = F*s

Explanation:

W = F*s*cos ∅ where ∅ refers to the angle between theforce and the displacement. Here, body moves in the direction of the force applied.

So, ∅ = 0° and hence cos ∅ = cos 0° = 1

∴ W= F*s*1 = Fs

Answer 2

Answer:



Hello...

Explanation:

When a force F is acting on a body produces displacement S in it in the direction of the force, the work done W by this force is the product of the force and the displacement, that is...

Work Done = Force x Displacement (In the direction of force)

W = F x S

You can also determine if the work done is Positive/Negative/Zero by multiplying with the cos of angle (cos ∅). This formula is given by,

W = F x S x cos ∅
