Momentum
========

Momentum is the product of mass and velocity and is conserved in isolated systems.

Key Concepts:
-------------
- Linear momentum and impulse
- Conservation of momentum
- Collisions (elastic and inelastic)

Sample Question:
----------------
A 2 kg object moving at 3 m/s collides with a 1 kg object at rest. What is the total momentum after the collision?

.. math::
   p_{total} = (2 \times 3) + (1 \times 0) = 6\ \text{kg m/s}
