energy
energy of body due to its position or shape
potential energy (pe)
formula of gravitational pe (GPE)
GPE = mgh m - mass g -gravitational field h - height
formula of elastic pe (EPE)
EPE = 1/2 kx^2 k - spring constant x - displacement of spring
energy of a moving body
kinetic energy
formula of kinetic energy
KE = 1/2 mv^2 m - mass v - velocity
the total amount of energy isolated from the rest of the universe always remains constant but can change from one form to another

conduction
what flow of energy that transfer energy by the movement of hot fluid from one place to another
convection
what flow of energy that transfer energy through light rays
radiation
