What do you mean by contact forces and non contact forces , explain with examples.
Solution
A contact force is defined as the force between two objects that are in physical contact. For example, kicking a soccer ball is a contact force since physical contact is between the foot and the ball.
A non-contact force is a force applied to an object by another body that is not in direct contact with it. Ex: Gravitational force, Electrostatic force, Magnetic forces
They are non contact forces because they can influence the objects without being in contact.
