A central force is a type of force that acts on an object towards a fixed point in space. This fixed point is known as the center of force and the force is always directed along the line connecting the object and the center of force.
A central force causes an object to move in a curved path, known as an orbit, around the center of force. The object will continue to move in this orbit unless acted upon by another force.
Central force is directly proportional to the angular momentum of an object. This means that as the central force increases, the angular momentum also increases, and vice versa.
Scattering is the process of an object being deflected or changing direction due to the interaction with a central force. It can occur when an object approaches the center of force or when it is already in an orbit.
Some examples of central force in nature include the gravitational force between the Sun and planets in our solar system, the electrostatic force between an electron and a proton in an atom, and the nuclear force between protons and neutrons in an atomic nucleus.
