Question

Define the term torque. State the SI and CGS units of torque.

Answer 1

1. A force makes an object rotate only if there is a point or axis on the object that does not move, called a pivot.
2. If an object is pivoted at a point, then a force applied to the object produces a turning effect on the object about an axis passing through the pivoted point.
3. The turning effect of a force is commonly known as the moment of the force or torque.
4. The SI unit of torque is $N-m$ and the C.G.S unit is $dyne-cm$
