== Kinetic Energy vs. Potential Energy ==
In physics, '''kinetic energy''' and '''potential energy''' are the two primary components of mechanical energy.<ref name="ref1" /><ref name="ref2" /> Kinetic energy is the energy an object possesses due to its motion.<ref name="ref3" /><ref name="ref4" /> Conversely, potential energy is the energy stored within an object based on its position, internal stresses, or configuration.<ref name="ref5" /> An object's total mechanical energy is the sum of its kinetic and potential energies.<ref name="ref3" /><ref name="ref2" /> Within a system subject only to conservative forces, such as gravity, the total mechanical energy remains constant, with energy converting between kinetic and potential forms.<ref name="ref1" />

=== Interconversion of Energy ===
Kinetic and potential energy can transform into one another. For example, a roller coaster car at the top of a hill has maximum potential energy and minimal kinetic energy. As it descends, its speed increases, converting the potential energy into kinetic energy. At the bottom of the hill, its kinetic energy is at a maximum, and its potential energy is at a minimum. As<ref name="ref1" /> the car begins to climb the next hill, its kinetic energy is converted back into potential energy, causing it to slow down.

This process demonstrates the principle of conservation of energy, which states that energy is not created or destroyed but only changes form. In real-world systems, some mechanical energy is often converted into other forms, such as heat, due to non-conservative forces like friction or air resistance.
