What is momentum?
PhysicsClassical mechanics
Quick Answer
Momentum is the quantity of motion an object has, equal to its mass multiplied by its velocity. It is conserved in isolated systems.
The Full Story
Momentum measures how difficult it is to stop a moving object. In classical physics, it is calculated as mass times velocity, and in a closed system the total momentum stays constant unless acted on by outside forces. The principle of conservation of momentum is essential in collisions, rocket motion, and many problems in physics. In relativity and quantum mechanics, momentum is still fundamental, though its mathematical treatment becomes more advanced.
