Work done in linear motion is defined by W=F.ds , what is it's analogue in rotational motion ?plz plz plz plz plz don't spam ​

Answer»

Answer:

Rotational Analogue of force in linear motion is torque.

τ

=

r

×

F

Force is NECESSARY for a body to do translational motion. Similarly it is the torque which is required to ROTATE a body. If net torque APPLIED on the body about the axis of ROTATION is zero, then the body DOESNOT rotate.
