Momentum is a physical quantity that is equal to the mass of an object multiplied by its velocity. Momentum is related to energy, and like energy it remains conserved in a closed system (a system where no energy enters or leaves). Classically, momentum is defined as
p=mv
where the bold P and v indicate vectors.
E=1/2mv²
Where w:kinetic energy is defined
Therefore,
2E/v=p
also note
dE/dV=p
That is, momentum can be used to measure the change in kinetic energy as an object changes velocity.
