Question

If there is an angle θ is in between force F and displacement s, then the value of work done will be :
A. Fs sin θ
B. Fs θ
C. Fscos θ
D. Fs tan θ

Answer 1

Answer:

FsCosi

Explanation:

If there is an angle θ is in between force F and displacement s, then the value of work done will be

FsCosi

Work done on an object along a given direction of motion is equal to the force times the displacement times the cosine of the angle.

Hete F = Force

s = Displacement

i = angle

hence  Work Done = Force * Displacement  * Cos(Angle)

=> Work Done = FsCosi

No work is done along a direction of motion if the force is perpendicular.

as Cos 90 = 0
