The Quantum Theory of General Relativity at Low Energies
... an old fallacy that effective Lagrangians can be used only at tree level. This sometimes still surfaces despite general knowledge to the contrary. “Effective field theory” is more than just the use of effective Lagangians. It implies a specific full field-theoretic treatment, with loops, renormaliza ...

In the general case, the final velocities are not determinable from just the initial velocities. If you know the velocity of one object after the collision, you can determine the other .

Kinetic energy
... Mechanical energy is the total amount of kinetic and potential energy in a system. In any given situation, energy may change from one form to another, but the total amount of energy remains constant: energy is conserved. The law of conservation of energy states that energy may change form but it c ...
