Momentum

So for this blog post, i was suppose to define what i think momentum is. so here is my definition: momentum is when an object is 'on the move'. So in other words its like when you throw a fast pitched ball, its hard to stop it immediately because of all the energy and momentum stored inside. the physics definition is: mass in motion. All objects have mass; so if an object is moving, then it has momentum - it has its mass in motion. The amount of momentum that an object has is dependent upon two variables: how much stuff is moving and how fast thestuff is moving. Momentum depends upon the variables mass and velocity. In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object. Momentum=Mass X Velocity. And for some odd reason, instead of using a 'M' to represent momentum, they use a 'P'. so the equation is: P=m*v.
