Apply the energy interaction model to the two-masses-over-a-pulley situation. Model this system as if the pulley is massless and frictionless, so you won't have to worry about energy systems associated with the pulley system.  Take the initial state to be you just release the masses (what is vi? what is delta-v?) Take the final state to be when the masses have a distance d and have speed but before they hit anything or out of string. (since d denotes a distance, it is a positive number: delta-y = +/- d, as appropriate) 2. when you substitute algebraic expressions for changes in individual energy systems in the algebraic representations of your particular Energy-Interaction Models, you will find the symbols m, M, g, v, and d useful. Watch your "minus signs"!

Relativistic Energy and Momentum

According to classical physics, time flow is the same for every observer. But according to einstein's theory, time flow is different for different observers. The idea that time flow is not the same for all may sound strange because we may not experience this effect in everyday life. This effect is only observed when an object moves with some velocity comparable to the velocity of light. This velocity is termed relativistic velocity.
