Understanding momentum and its changes

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.

What does the rate of change of momentum relate to?

Click to reveal answer

The rate of change of momentum relates to the force applied; force is equal to the change in momentum over time (F = Δp/Δt).

Key notes

Important points to keep in mind

Momentum is mass times velocity.

F = Δp/Δt links force and momentum change.

Collisions exhibit conservation of momentum.

Momentum depends on speed and mass.

Safety features utilize momentum principles.
