Momentum in classical physics is a measure of an object's motion. It is the product of an object's mass and velocity. In other words, it is the quantity of motion an object has.
Momentum is calculated by multiplying an object's mass (m) by its velocity (v). The formula is p = m * v. The units of momentum are kg * m/s.
The principle of conservation of momentum states that the total momentum of a closed system remains constant over time. This means that the total momentum before an event or interaction is equal to the total momentum after the event or interaction.
Some real-life examples of momentum include a moving car, a swinging pendulum, a person running, a ball rolling down a hill, and a rocket launching into space.
According to Newton's second law of motion, force is equal to the rate of change of momentum. This means that the greater the force applied to an object, the greater the change in its momentum. Additionally, the direction of the force and the direction of the change in momentum are the same.
