Mechanical Energy
Definition
-
Kinetic energy
Definition: Work needed to accelerate a body of a given mass from rest to its stated velocity (Always positive or zero)
-
Formula: KE = 1/2 mv^2, KE = 1/2 (mass)(speed)^2
-
Elastic potential energy
Definition: Potential energy stored as a result of deformation of an elastic object, such as stretching of a spring (Always positive or zero)
-
Formula: EPE = 1/2 kx^2, EPE = 1/2 (spring constant)(displacement of spring from neutral position)^2, Spring force (Fsp) = -kx, Fsp = -(spring constant)(displacement from equilibrium)
-
Other form of energy
-
Electrical energy: Electricity is delivered by tiny charged particles called electrons, typically moving through a wire
Nuclear energy: Energy stored in the particles inside an atomic nucleus. Large amount of energy can be released when the nuclei are combined or split apart
