Question

Write true or false.

All forces are contact forces.

• A. True
• B. False

Answer 1

The correct option is B False

1. Contact forces are defined as the force which is applied by the bodies in contact. For the application of the contact force contact between the bodies is necessary it may be directly or indirectly.
2. Frictional force and muscular force are contact forces.
3. Some forces like gravitational force and magnetic force do not require any type of contact for the action and so these forces are not contact forces.

Hence the given statement is false.
