the total amount of potential and kinetic energy of a system; PE+KE Total Mechanical Energy (TME)
energy due to motion of object or atoms/particles kinetic energy (KE)
If two objects are moving with the same velocity, how would one object have greater kinetic energy? the object would have more mass
mass x g x height is the formula for what? gravitational potential energy (GPE)
1/2 x m x v^2 is the formula for what? kinetic energy (KE)
states that energy cannot be created or destroyed only transformed law of conservation of energy
