Momentum alone

The faster an object is moving and the harder it is to stop, some like as bullet hits and gets embedded in a solid block – whether it be a automobile or baseball. Momentum of an object is equal to the mass times the velocity.
Some about the momentum:
The symbol for momentum is ‘p’
p=m*v           (m=mass, v=velocity)
Momentum is a vector, pointing in the direction of the velocity.

Momentum=mass of object x velocity of object
Kinetic energy=(mass of object x (velocity of object)2)/2
