Question

why is work done zero when angle between force and displacement is 90°?

Answer 1

$\huge\boxed{\texttt{\fcolorbox{purple}{yellow}{Heya Guys!!!}}}$

The formula for Work is

Work=Force×Displacement×CosA

Where A is the angle between Force and Displacement.

Cos 90°=0

That's why whenever you walk, the work done by gravity is zero.

Answer 2

Answer:Work done =0, when angle between 2 objects is 90 degree.

Explanation: We know that,

W = Fscosteta

Given angle is 90 degree.

We know that cos 90 = 0 degree

Substitute cos 90 = 0 degree in the formula ''W = Fscosteta''.

W = F × s × 0

W = 0

Therefore work done is 0, when angle formed by 2 objects is 90

degree.
