Non-contact force is a type of force that acts on an object without any physical contact with it. It occurs when objects do not have physical contact between them or when a force is applied without any interaction. Non-contact forces are different from contact forces, which act between objects in contact with each other. Examples of non-contact forces include:
-
Gravitational force: This is the force of attraction between two objects due to their masses. It is a non-contact force because it acts over a distance without any physical contact between the objects.
-
Electrostatic force: This is the force of attraction or repulsion between two charged objects. It is a non-contact force because it acts over a distance without any physical contact between the objects.
-
Magnetic force: This is the force of attraction or repulsion between two magnets or a magnet and a magnetic material. It is a non-contact force because it acts over a distance without any physical contact between the objects.
-
Nuclear force: This is the force that holds the nucleus of an atom together. It is a non-contact force because it acts over a distance without any physical contact between the particles in the nucleus.
Non-contact forces are different from contact forces because they do not require physical contact between objects. They can influence objects without being in contact with them.
