An object loses its energy, when it performs work, whereas it gains energy when the work is performed on it. Energy is broadly classified as kinetic energy and potential energy. While kinetic energy is the energy which an object contains because of a particular motion.
The ability of the body to exert a push or a pull against natural forces like gravity identifies what kind of energy it is. When an object is at rest, the body is said to possess potential energy. In another case, when the object is in motion, then it is said to possess kinetic energy.
Potential energy (PE) is stored energy due to position or state. a raised hammer has PE due to gravity. fuel and explosives have Chemical PE. a coiled spring or a drawn bow also have PE due to their state.
KE is the kinetic energy in Joules (J). m is the mass of the object in kilograms (kg). v is the velocity of the object in meters per second (m/s). Potential Energy, on the other hand, is the energy an object possesses due to its position or configuration relative to a reference point.
What's the difference between Kinetic Energy and Potential Energy? Kinetic energy is energy possessed by a body by virtue of its movement. Potential energy is the energy possessed by a body by virtue of its position or state.
Thermal potential energy is PE at the atomic and molecular levels, when the particles show the potential of converting into KE. On the other hand, thermal kinetic energy is when the atoms and molecules start moving due to heat.
\[KE=\frac{1}{2}mv^{2}\] where KE is kinetic energy, m is mass, and v is velocity. This definition should make sense: big things moving fast have the most energy, the most ability to shove other things or knock them over, etc. Potential energy is energy that comes from position and a force.
