Joule (J) | The SI Unit of work and energy; it is a derived unit |
Kinetic Energy | The energy that an object possesses because of its motion. |
Potential Energy | Energy resulting from the position or state of an object. |
Power | Power is the time-rate of doing work. |
Conservation of Energy | In any transfer of energy among objects in a close system, the total energy of the system remains constant. The change in energy of a system is equal to the sum of the change in its kinetic energy, the change in its potential energy, and the change in its |
Elastic Potential Energy | When work is done on a spring by compressing or stretching it, potential energy is stored in the spring. |
Energy | The capacity of a system to do work. |
Gravitational Potential Energy | When work is done on an object by moving it against an Gravitational Field, the objects acquires gravitational potential energy. |
Internal Energy | The total energy of a system or object, including its potential energy and its kinetic energy. |
Mechanical Energy | A form of energy resulting from physical changes that encompasses both kinetic and potential energy. |
Spring | An elastic body, such as a coil of metal, that recovers its shape after being compressed, bent, or stretched. |
Spring Constant | The constant of proportionality in the equation for the force required to stretch or compress a spring :Fs=Kx |
Total Mechanical Energy | The sum of the kinetic and potential energies in a mechanical system. |
Work | Work is done on an object when a force displaces the object. |
Spring Potential Energy | The potential energy held in an elongated spring. |
