Mechanical Energy
Elastic Energy
Definition: Elastic potential energy (EPE) is potential energy stored as a result of deformation of an elastic object, such as the stretching of a spring.
-
Spring Force: The force produced by the free end of the spring. The spring force is not constant as an object is pushed or pulled.
Spring Force (Fsp) = - kx

-
-
Spring Constant: Springs in series have same force passing through them, as each contributes to the total deflection.
Springs in parallel have same deflection, and total force is split among them. For springs in parallel, individual spring rates add directly.
-
-
SI unit: Joules (J)
Work definition: The energy transferred to or from a system by a force that acts on it and makes a displacement or a change of condition(s).
Energy definition: The ability to do work or to cause change. When something is able to change its environment or itself, it has energy.
-
Kinetic Energy
-
Definition:
The energy of a moving object because of its motion. The kinetic energy of a moving object depends on the object’s mass and its speed.
-
Potential Energy
-
Definition: Potential energy (PE) is the stored energy possessed by a body by virtue of its position relative to others, stresses within itself, and other factors.
-
The law of conservation of energy: Energy cannot be created or destroyed; it may be converted from one form into another, but the total amount of energy never changes.

-
Other forms of energy: Chemical, Electrical, Nuclear
