Gravitational force is the attractive force between two masses due to their mass and distance. It is described by Newton’s law of universal gravitation which states that the force is directly proportional to the product of the masses and inversely ...

Kinetic energy is the energy possessed by an object due to its motion. It is calculated using the formula KE = (1/2) mv² where m is the mass and v is the velocity. Kinetic energy increases with the square of ...
Friction is a force that opposes the relative motion between two surfaces in contact. It arises due to microscopic irregularities and adhesive interactions. There are two main types of friction: static friction which prevents motion and kinetic friction which acts ...
An elastic collision is a type of collision where both momentum and kinetic energy are conserved. During this interaction, objects may deform temporarily but return to their original shapes afterward. Examples include collisions between billiard balls or gas molecules, demonstrating ...
An elastic collision is one in which both momentum and kinetic energy are conserved. During the collision, the objects may deform momentarily but return to their original shapes without loss of energy. Examples include collisions between billiard balls or gas ...
