... Conservation of Linear Momentum in a Two Particle System Consider an isolated system with two particles that do not have any external forces exerting on it. What is the impact of Newton’s 3rd Law? If particle#1 exerts force on particle #2, there must be another force that the particle #2 exerts on ...

... The motion of a pendulum is a classic example of mechanical energy conservation. A pendulum consists of a mass (known as a bob) attached by a string to a pivot point. As the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion. Neglecting air resistance (which wou ...
