Momentum
Momentum
Momentum (pronounced: /moʊˈmɛntəm/) is a fundamental concept in physics that describes the motion of an object. The term is derived from the Latin word 'movimentum', which means 'movement'.
Definition
In physics, momentum is the product of the mass of an object and its velocity. It is a vector quantity, meaning it has both magnitude and direction. The SI unit for momentum is kilogram meter per second (kg·m/s).
Formula
The formula for momentum (p) is:
p = m * v
where:
- m is the mass of the object (in kilograms)
- v is the velocity of the object (in meters per second)
Conservation of Momentum
The Conservation of Momentum is a fundamental principle in physics. It states that the total momentum of a closed system (i.e., a system that does not interact with external forces) is constant.
Impulse
Impulse is closely related to momentum. It is the change in momentum of an object when a force is applied over a period of time.
Angular Momentum
Angular Momentum is a measure of the amount of rotation an object has, taking into account its mass, shape, and speed. It is the rotational equivalent of linear momentum.
