Question

Give two examples of the turning effect of force.

Answer 1

If a body under the action of a net external force is allowed to rotate about a pivot, the body will tend to turn in the direction of the applied force.

Examples of turning effect of force:

1. A person pushing a swing will make the swing rotate about its pivot.
2. A worker applies a force to a spanner to rotate a nut.
3. A person removes a bottle’s cork by pushing down the bottle opener’s lever.
4. A force is applied to a doorknob and the door swings open about its hinge.
5. A driver can turn a steering wheel by applying a force on its rim.
