SUMMARY

The best equation to find momentum is defined as \(\mathbf{p} = m\mathbf{v}\), where \(\mathbf{p}\) represents momentum, \(m\) is mass, and \(\mathbf{v}\) is velocity. Additionally, the relationship between force and momentum is expressed as \(\mathbf{F} = \frac{d\mathbf{p}}{dt}\). Momentum is measured in units of kilogram-meters/second (kg*m/s). For advanced contexts, the equation E^2 - (pc)^2 - p^2c^4 = 0 may also be relevant.

PREREQUISITES
  • Understanding of basic physics concepts, particularly momentum
  • Familiarity with vector notation in physics
  • Knowledge of units of measurement in physics
  • Basic calculus for understanding the relationship between force and momentum
NEXT STEPS
  • Research the implications of Newton's Second Law in relation to momentum
  • Study the concept of conservation of momentum in closed systems
  • Explore relativistic momentum and its equations
  • Learn about kinetic energy and its relationship with momentum
USEFUL FOR

Students of physics, educators teaching mechanics, and professionals in fields requiring an understanding of momentum and its applications.

Probably Use

\vec p = m \vec v
Or

\vec F =\frac{d\vec p }{dt}

The momentum of what? Given what? The definition of momentum of a particle is

\mathbf{p} = m\mathbf{v}

Once you know the mass and the velocity you know the momentum.
 
What are the units momentum is measured in?
