The Physics of BilliardsNewtons LawsFirst Law An purpose at rest waistcloth at rest. If it is moving, the object will continue to move with the same velocity. reciprocal ohm Law The net force on an object is compare to the harvest-tide of the objects pickle and its acceleration. (F = ma)Once the cue evening gown begins to roll there be no net external forces acting in the cardinal- crackpot system indeed the a must be = 0. Acceleration is the rate of change of velocity. If acceleration is 0 there is no change in velocity. When the two chunks jar the only forces acting are internal and they do not refer the net force. This means that the center of mass of the system continues to move ship with the same velocity and direction after the collision.Third Law When two objects interact, the forces acting on them from each other are always equal in magnitude and opposite in direction.CollisionsElastic The Kinetic zippo of the system is conserved after the collision.Ex. T he collision of a cue ball with an object ball.Head on The Kinetic energy of the cue ball is transferred almost entirely to the object ball with a small sum up of energy lost in sound.The two object system is unlikeable and isolated so linear momentum is conserved and the collision is pliant so the kinetic energy is conserved. The balls are equal in mass som1v1i = m1v1f + m2v2f (linear momentum) m1v1i2 = m1v1f2 + m2v2f2 (kinetic energy)v1f = (m1 - m2)/(m1 + m2) v1iv2f = 2m1/(m1 + m2) v1iIf m1 = m2, the above equations reduce to v1f = 0 and v2f = v1iBasically the cue ball is ab initio moving, stops suddenly when it hits the object ball at initially at rest which after the collision takes off with the initial accelerate of the cue ball.After CollisionRollingA rolling object has two types of kinetic energy.Rotational Energy Icomw2
