Kinetic energy is always conserved
WebIf the kinetic energy of the system does not remain constant then the collision is said to be inelastic. But the total energy is conserved in both the cases. Let us first discuss elastic collisions. C , Study of elastic collisions W e understand that in the case of an elastic collision both the equations 3 and 3 will hold. Web26 aug. 2024 · In physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time.

According to it, energy can neither be created nor be destroyed; it can only be converted from one form to another. For instance, kinetic energy can be converted into heat energy and vice versa. The amount of energy, however, will remain the same.
WebThe mechanical energy of a system, or the sum of the kinetic and potential energy, is conserved when only conservative forces are acting on objects in the system. If a nonconservative force, such as friction, acts on an object, the total mechanical energy is different than what it was initially. WebMomentum does not always change and not be conserved because when the kinetic energy is conserved by default, the collision is conserved automatically. The momentum required when the change of speed happens during a collision does not change. Even after the collision, it is said to be conserved.
