Momentum
Leaving Cert Physics · Forces and Motion
Higher Level
The product of the mass of a body and its velocity, measured in kg m s⁻¹ and pointing in the same direction as the velocity. A large value makes a body harder to stop, which is why it is central to the study of collisions.
Ordinary Level
The mass of an object multiplied by its velocity. A lorry has far more of it than a bicycle moving at the same speed.
