non-contact forces
1 answer
Non-contact forces are forces that act on an object without physically touching it. These forces can occur over a distance, without any direct contact or interaction between the objects involved. Examples of non-contact forces include gravitational force, electric force, and magnetic force. Gravitational force is the force of attraction between two objects due to their mass. Electric force is the force of attraction or repulsion between charged particles. Magnetic force is the force exerted by magnets or magnetic fields on other magnets or magnetic materials. These forces are fundamental in explaining various phenomena in physics and have significant applications in everyday life.
