Physics Chapter on Energy and Work

The ability to do work. It can exist in various forms, such as kinetic energy and potential energy.

The energy an object possesses due to its motion. It depends on the object's mass and velocity. The greater the mass or velocity, the greater the kinetic energy.

The energy an object possesses due to its position or configuration relative to a force field. Examples include gravitational potential energy and stored energy in a spring.

The work done by a force on an object is defined as the force multiplied by the distance moved in the direction of the force.

Energy cannot be created or destroyed; it can only be transformed from one form to another.

The temperature at which all molecular motion ceases. This is the lowest possible temperature.

The process of splitting heavy atomic nuclei into lighter ones, releasing vast amounts of energy.

The process of combining light atomic nuclei to form heavier ones, also releasing significant energy. An example is the fusion of hydrogen into helium in the Sun.
