Momentum = mass velocity. You can calculate momentum for every object in motion with a defined mass. The more massive and faster moving an object, the greater the magnitude of momentum.\r\n
The angular momentum equation
\r\nPhysics also features angular momentum, L. The equation for angular momentum looks like this:\r\n\r\n
- \r\n\t
- L = angular momentum \r\n\t
- / = the moment of inertia \r\n\t
- W = the angular velocity \r\n


The principle of conservation of angular momentum states that angular momentum is conserved if no net torques are involved.
\r\nThis principle comes in handy in all sorts of problems, such as when two ice skaters start off holding each other close while spinning but then end up at arms length. First calculate the momentum of both trolleys before the collision: 2 kg trolley = 2 3 = 6 kg m/s 4 kg trolley = 8 0 = 0 kg m/s Total momentum before collision = 6 + 0 = 6 kg m/s Total. As a result, less massive objects can have more momentum than more massive objects (if the less massive object is moving faster), and slower objects can have more momentum than faster objects (if the slower object has more mass). First calculate the momentum of both trolleys before the collision: 2 kg trolley = 2 3 = 6 kg m/s 8 kg trolley = 8 0 = 0 kg m/s Total momentum before collision = 6 + 0 = 6 kg m/s Total. Given their initial angular velocity, you can find their final angular velocity, because angular momentum is conserved:\r\n\r\n
