Momentum is a fundamental quantity in physics, defined as the product of an object's mass and velocity: p = m 脳 v.

This calculator helps you determine the momentum, mass, or velocity of an object when the other two variables are known.

About Momentum

Momentum is a vector quantity that represents the product of an object's mass and velocity. It is a fundamental concept in physics and is conserved in closed systems.

Key Concepts:
  • Momentum (p): The product of mass and velocity, measured in kilogram meters per second (kg路m/s) or newton-seconds (N路s).
  • Mass (m): The amount of matter in an object, measured in kilograms (kg).
  • Velocity (v): The rate of change of position, measured in meters per second (m/s).
  • Impulse: The change in momentum, equal to the force multiplied by the time interval (F路螖t).
  • Conservation of Momentum: In a closed system, the total momentum remains constant if no external forces act on the system.
The Momentum Equation:

p = m 脳 v

Where:

  • p is the momentum
  • m is the mass
  • v is the velocity

For solving for mass or velocity:

m = p / v

v = p / m

Momentum in Different Contexts:
  • Classical Mechanics: Linear momentum is conserved in elastic and inelastic collisions.
  • Relativistic Mechanics: At speeds approaching the speed of light, relativistic momentum must be considered: p = 纬mv, where 纬 is the Lorentz factor.
  • Quantum Mechanics: Momentum becomes a property associated with waves: p = h/位, where h is Planck's constant and 位 is wavelength.
  • Angular Momentum: For rotating objects, angular momentum (L = I 脳 蠅) is also conserved in the absence of external torques.
Applications:
  • Collisions: Understanding car crashes, billiard ball impacts, and atomic collisions.
  • Propulsion: Rockets, jet engines, and propellers all rely on momentum exchange.
  • Sports: Baseball pitches, football kicks, and golf swings involve momentum transfer.
  • Transportation: Braking distances increase with greater vehicle momentum.
  • Particle Physics: Analyzing particle interactions in accelerators relies on momentum conservation.

Understanding Momentum

Momentum is a key concept in Physics that helps us understand how objects move. It's calculated by multiplying an object's mass by its velocity. The formula is simple: p = m 脳 v. This means that the heavier an object is or the faster it moves, the more momentum it has. Knowing how to calculate momentum is valuable in many real-world scenarios, from Sports to vehicle dynamics.
