The simplicity of momentum

The astronaut has greater massand slower velocity

The wrench has less massand 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.

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.

Conservation of Linear Momentum

The change in momentum of a system is equal to the impulse put on the system.
