Momentum Equation Momentum = mass x velocity Equation is p=mv p is used to represent momentum
Momentum Example Find the momentum of a 75 kg speed skater moving forward at 16 m/s.
Momentum Example momentum = mv Momentum = (75 kg)(16m/s) Momentum= 1200 kg m/s forward
Conservation of Momentum The total amount of momentum in a system is conserved
Conservation of Momentum If two vehicles with different masses are traveling with different velocities and they hit head on, the momentum of the two cars before the collision is the same after the collision.
Gravity Gravitational force is determined by the distance between the two masses. Everything falls at an acceleration of 9.8 m/s 2 in the absence of air resistance Gravity is opposed by air resistance
