kinetic energy definition
the energy possessed by moving objects
kinetic energy formula
KE = 1/2mv**2
principal of conservation of energy
the total energy of a system always remains constant but it can change from one form to another
potential energy definition
the energy possessed by objects due to their position or configuration
types of potential energy (3)
gravitational potential energy
elastic potential energy
electric potential energy
GPE definition
energy possessed due to its height from the surface of the earth
GPE formula
GPE = mgh
EPE (elastic potential energy) definition
energy possessed due to stretching/compression (straining)
EPE (electric potential energy) definition
energy acquired by charged particles in electric field
