What is Momentum?

In physics, momentum is the “mass in motion” of an object. It is a fundamental vector quantity defined as the product of an object’s mass and its velocity. The concept of momentum is a cornerstone of classical mechanics, and it is closely related to Newton’s Second Law of Motion. The principle of conservation of momentum, which states that the total momentum of a system remains constant if no external forces act on it, is one of the most important laws in physics. It is used to analyze collisions and explosions, from car crashes to the recoil of a firearm.

This calculator is an invaluable tool for students, teachers, engineers, and anyone with an interest in physics. It simplifies complex calculations and helps in visualizing the relationships between mass, velocity, and momentum, deepening your understanding of these core physics concepts.
