Forces and motion • Momentum

Key concepts

What you'll likely be quizzed about

  • Momentum is defined as the product of an object's mass and velocity.
  • The formula for momentum (p) is given by p = mv, where m is mass and v is velocity.
  • An object has greater momentum if it is more massive or moving faster.
