1. Impulse Momentum 1 Conservation

2. Impulse Momentum 2 The simplicity of momentum The astronaut has greater mass and slower velocity The wrench has less mass and faster velocity When added together as vectors the total momentum is still zero. The initial momentum is zero because the velocity of both astronaut and wrench are zero.

3. Impulse Momentum 3 Definition of Linear Momentum The linear momentum of an particle is simply its mass times its velocity Note that it is also a vector! The total momentum of a system of particles is the sum of the momentum of the individual particles.

4. Impulse Momentum 4 Conservation of Linear Momentum The change in momentum of a system is equal to the impulse put on the system.
