Formula
p = m x v, where p = momentum (kg*m/s), m = mass (kg), v = velocity (m/s). Vector quantity. Conservation: total momentum before = total after in closed system.
Example Calculations
Moving Object
Input: Mass: 5 kg, Velocity: 10 m/s
Result: Momentum: 50 kg*m/s
Collision
Input: 2kg at 3m/s hits 4kg at rest (perfectly inelastic)
Result: Combined velocity: 1 m/s
Football Player
Input: Mass: 100 kg, Velocity: 8 m/s
Result: Momentum: 800 kg*m/s

Frequently Asked Questions
What is momentum?
p = mv. Product of mass and velocity. Vector quantity with magnitude and direction.
Conservation of momentum?
In closed systems, total momentum before collision = total after. Used for crash analysis, rockets.
Elastic vs inelastic collisions?
Elastic: both momentum and KE conserved. Inelastic: momentum conserved, KE not.
Momentum vs force?
Force changes momentum over time (F = dp/dt). Momentum is a property; force changes it.
Why momentum matters?
Fundamental conserved quantity. Essential for collisions, rockets, fluid dynamics, quantum mechanics.
