Kinetic energy is conserved in a system when there are no external forces acting on the system, meaning that the total amount of kinetic energy remains constant.
Kinetic energy is not conserved in inelastic collisions because some of the initial kinetic energy is transformed into other forms of energy, such as heat or sound, during the collision. This results in a decrease in the total kinetic energy of the system after the collision.
Mechanical energy is always conserved in a closed system. It can exist as potential energy (stored energy) and kinetic energy (energy of motion). This conservation principle is known as the law of conservation of mechanical energy.
Yes, kinetic energy is conserved in an elastic collision, meaning the total kinetic energy before the collision is equal to the total kinetic energy after the collision.
In an isolated system, both momentum and kinetic energy are conserved during a collision. Momentum is conserved because the total momentum before the collision is equal to the total momentum after the collision. Kinetic energy is conserved if the collision is perfectly elastic, meaning there is no energy lost to other forms (e.g., heat or sound).
The sum of potential and kinetic energy is called "mechanical energy". This is NOT conserved, though - unless you consider the microscopic scale, in which case (for example) heat energy is a type of kinetic energy. In this case, the sum is simply the total energy, and the total energy IS conserved.
