Momentum is the the quantity of motion of a moving body, measured as a product of its mass and velocity.

The conversation of momentum is is a rule that says the total momentum of a system won't change unless an external force acts on it.

The formula for momentum is momentum = mass x velocity or p = mv.

The letter p is the letter used to represent momentum because m is used for mass and momentum needed a different letter then m.

A heavy truck has the same momentum as a small motorcycle because If two things crash together, their total momentum is the same before and after the collision.

In an elastic collision, no kinetic energy is lost. In an inelastic collision, some of the energy will be lost to heat or sound or light or some other energy.

Elastic Collision Example

Inelastic Collision Example

the type of collision that would throw a piece of clay on the ground would be the inelastic collision because the clay would be thrown either to the side or to the front depending on which car the clay is on, when the cars make impact.

The angular momentum is the quantity of rotation of a body, which is the product of its moment of inertia and its angular velocity.The orbital angular momentum for an atomic electron can be visualized in terms of a vector model where the angular momentum vector is seen as processing about a direction in space. While the angular momentum vector has the magnitude shown, only a maximum of l units can be measured along a given direction, where  is the orbital quantum number.
