Contact forces are forces that act between two objects that are physically touching each other. Examples of contact forces include friction, air resistance, and tension in a rope.
What are non-contact forces?Non-contact forces, on the other hand, are forces that act between two objects that are not physically touching each other. These forces can act over a distance and include gravitational forces, magnetic forces, and electrostatic forces.
In summary, the main difference between contact and non-contact forces is whether or not the objects are physically touching each other. Contact forces act between objects in contact, while non-contact forces act between objects that are not in contact.
