WORK IS DONE WHENEVER A FORCE MAKES SOMETHING MOVE. Greater the force, greater the distance, greater the work.
Work Done = Force x Distance Moved In Same Direction
W = F x D
Objects or particles store energy because of their position the general name for this is potential energy 🙂
Law of conservation of energy- Energy can be stored or transformed, but it cannot be created or destroyed
Energy can be wasted though - Thermal energy, sound, etc.
Work done = energy transformed
GPE - Potential energy due to position of an object
Gravitational Potential energy = $mgh$
Kinetic energy = $1/2mv^2$
Energy is scalar
OFTEN -
Max height = mgh = 0.5mv^2
