Introduction to loss of kinetic energy:
Different types of energy are there e.g., electric energy, chemical energy, heat energy, gravitational energy etc. They can be categorized in two key classes’ namely, kinetic energy and potential energy. Kinetic energy of a body is the kind of energy which it gains due to its motion.
So calculating this work one easily obtains the following:
It can be better known by examples which show transformation of kinetic energy to other forms and vice-versa. For example, chemical energy obtained from food is used by a cyclist to speed up his bicycle up to a chosen pace. Without rest of work, this pace is maintained, except to conquer friction and air-resistance. The energy here has been converted into kinetic energy, the energy of motion.
Loss of Kinetic Energy in Different Terms:
Energy can neither be created nor be destroyed; it is transformed from one form to another. So any alter in kinetic energy consequences in alteration of potential energy e.g. kinetic energy within the cyclist which is moving as well as the bicycle is converted to some other forms. Also, if the cyclist encounters a hill which is high enough to board up, kinetic energy will be largely converted to potential energy due to gravitation, which is released by freewheeling down the later side of the hill, so that the bicycle comes to a complete halt at the top. As the bicycle lost a few energy due to friction, without further pedaling, it will not get back all of its speed.

Loss of Kinetic Energy in Elastic Collision
Elastic collision in which no kinetic energy is lost is called perfect elastic collision. Macroscopic collisions are inelastic so they do not conserve kinetic energy and the total energy is conserved. In inelastic collision kinetic energy is changed or lost resulting in work done. In this kinetic energy is changed or lost as heat, sound, binding energy or other kinds of energy. This Kinetic energy passes from one object to the other. While playing billiards, player strikes, cue balls through a cue stick; kinetic energy is given by player to the cue ball. Again, cue ball collide with one more ball, then it will slow down and the ball with which it collided, will pace up to a speed, with the passage of kinetic energy.

Conclusion for Loss in Kinetic Energy
Energy can neither be created nor be destroyed. All forms of energy are categorized in two i.e. kinetic energy and potential energy. And, loss in kinetic energy will result in gain of potential energy.
