What is impulse physics?

Impulse physics is a branch of physics that deals with the study of the change in momentum of an object when it experiences an external force. The momentum of an object is defined as the product of its mass and velocity. Impulse is the change in momentum of an object, typically caused by a collision with another object. It is calculated as the product of the force applied to the object and the time over which the force acts.

The principle of conservation of momentum is a fundamental concept in impulse physics, stating that in the absence of external forces, the total momentum of a system remains constant. This principle is often used to analyze collisions between objects, where the total momentum of the system must be conserved before and after the collision.

Impulse physics is widely applied in many fields, including engineering, sports, and transportation. For example, understanding impulse physics is important in designing safety devices for vehicles and in analyzing the effectiveness of sports equipment.
