Potential Energy and Kinetic Energy (2)

Kinetic energy

Energy possessed by a moving object

Kinetic energy formula

m=mass, v=velocity

Graph Force (F) - spring extension (x)

Area under the graph

Equivalent to elastic potential energy

Formula for calculating the work done

Full form of F in elastic potential energy formula Elastic potential energy = 1/2 Fx

F is the stretching or compression force in N

Full form of F in elastic potential energy formula Elastic potential energy = 1/2 Fx

x is the displacement from the equilibrium position in m
