Kinetic Energy→↓
The kinetic energy of an object is the energy which it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body in decelerating from its current speed to a state of rest.
Potential energy is one kind of the energy that we learned in our physics class. Potential energy is the energy stored in a body or in a system due to its position in a force field or due to its configuration. We calculate potential energy in J (joule). It's the SI unit of work and energy. The term "potential energy" was coined by the 19th century Scottish engineer and physicist William Rankine.
Gravitation energy→↓
Gravitaion energy is the energy that act on any object in the world due to the gravity. If an object falls from one point to another point inside a gravitational field, the force of gravity will do positive work on the object, and the gravitational potential energy will decrease by the same amount.
Thermal energy→↓
Thermal energy is the energy that makes objects hot. It is a form of kinetic energy at the molecular level, the movements of atoms and molecules. It is the translation of two different energy. For example, Hot water has more kinetic energy then cold water because there are more molecule acting in the hot water than the cold water.
Elastic energy→↓
Elastic energy is the potential mechanical energy stored in the configuration of a material or physical system as work is performed to distort its volume or shape.
Chemical Energy→↓
Chemical energy is the potential of a chemical substance to undergo a transformation through a chemical reaction or to transform other chemical substances. Breaking or making of chemical bonds involves energy, which may be either absorbed or evolved from a chemical system.
