# What is momentum?

• The faster a car goes the more momentum it gains.

• Once a thing gets started it just keeps on going and it has energy.

• it can be defined as "live force" i.e.the product between mass and velocity and, then, a vector quantity !!!!

• you can consider it a form of contained (potential) energy resulting from a mass in motion. what it is, precisely, is mass times velocity. really, that represents a way of describing the contained kinetic energy using a non-energy parameter. (kinetic energy is 0.5*mass*velocity^2). momentum is the derivative of that (dE=d(1/2* m *v^2)=2*(1/2)*m*v=mv=momentum, so it is a way of quantifying how the kinetic energy will change if a force is applied giving an acceleration to the object. that difference would be lost contained energy, or a form of counteracted potential energy.

It is a measure of resistance to change in kinetic energy of an object in motion in the face of an applied force.

• Momentum is a measure of the tendency of a body in motion to continue in motion in a straight line. Momentum is the product of mass and velocity. If 2 bodies collide and stick together, their combined motion is according to the proportion of momentum each had.

• Momentum is related to the inertia of a moving object. The greater the momentum of a moving object, the more difficult the object is to stop. There are two types of momentum. Linear momentum is the product of the mass and the velocity of an object. Momentum is a vector quantity.

• Momentum can be defined as “mass in motion”. All the 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 the stuff is moving. Momentum is depends upon the variables mass and velocity.
Momentum = mass x velocity
p = mv
This equation illustrates that momentum is directly proportional to an object’s mass and object’s velocity.
