Momentum is a property of an object that describes its motion. It is defined as the product of an object's mass and velocity.
Momentum is calculated by multiplying an object's mass (in kilograms) by its velocity (in meters per second).
The conservation of momentum states that the total momentum of a closed system remains constant, meaning that the combined momentum of all objects in the system before and after an interaction will be the same.
According to Newton's second law, the force acting on an object is equal to its mass multiplied by its acceleration. Since acceleration is the change in velocity over time, and momentum is mass times velocity, we can see that force is also equal to the change in momentum over time.
The greater the mass and velocity of an object, the greater its momentum will be. This means that an object with a larger mass or a higher velocity will be harder to stop or change its direction of motion.
