What are contact and non contact forces? Give 2 examples of each.
Solution
Contact forces are those forces in which direct contact between the two bodies is required. For example, when a batsman in a game of cricket hits a ball there is a direct contact between the ball and bat and the force in this case is a contact force. Frictional force is good example of contact force.
Non contact forces are those forces in which two bodies interact without any direct contact. For example, when a ball is thrown it comes back to earth because of gravitational force of the earth. In this case field force forces a body to drop down without any direct contact.
