Momentum Theory

What Is Momentum?

Momentum is the measure of motion in a body and is directly proportional to both mass and velocity. It is conserved in isolated systems.

The Momentum Formula

The momentum (p) of an object is calculated using:

p = m × v

Where:

  • p = momentum (kg·m/s)
  • m = mass (kg)
  • v = velocity (m/s)

Momentum is a vector quantity, meaning it has both magnitude and direction.

Key Concepts
  • Conservation of Momentum: In an isolated system, the total momentum remains constant.
  • Impulse: The change in momentum of an object when a force is applied over time.
  • Momentum vs. Kinetic Energy: While related, these are distinct concepts in physics.
Example Calculation

Given:

  • Mass = 10 kg
  • Velocity = 5 m/s

Then:

p = 10 kg × 5 m/s = 50 kg·m/s

Remember: Always use consistent units when performing calculations. This calculator handles conversions automatically.
