Answer 2

Answer:

The turning effect of force is called Torque.

The turning effect of a force applied on the body about an axis is due to the moment of force or torque.

Explanation:

The factors affecting the turning effect of a body:

(i) The magnitude of a force applied.

(ii) The distance of the line of action of the force from the axis of rotation.

Examples:

A person pushing a swing will make the swing rotate about its pivot.

 A force is applied to a spanner to rotate a nut.
