Essay The Law Of Conservation Of Energy
Billiards uses some of the most fundamental principles found in physics. The game uses all three of Newton’s laws and the associated ideas of collisions, momentum, energy, forces, and friction. There are two fundamental laws used in this game that are very important.
First, the law of conservation of energy states that in an isolated system, the total energy remains constant. This game uses mechanical energy specifically, and also the conservation of energy in an elastic collision. If there are no external forces acting upon the system, the amount of total energy present before the collision is the same after the collision. This is represented by the expression:
½(m1v012) + ½(m2v022) = ½(m1vf12) + (½m2vf22)
Second, the law of conservation of momentum states that in an isolated system, momentum is conserved. Momentum, equals P=MV g*m/s. Regardless of whether the collision is elastic or inelastic, the total momentum…
