mévectors

Mevectors, short for momentum vectors, are a fundamental concept in physics and engineering. A momentum vector is a mathematical representation that combines both direction and magnitude of a massive object's linear momentum in a single vector quantity.

Momentum, being the product of mass and velocity of an object, is inherently a vector quantity. It possesses both magnitude, referring to the amount of momentum, and direction, pointing towards the direction of the momentum. Consequently, the momentum vector is used to graphically represent this directional motion. This concept is crucial in multiple branches of physics, including mechanics, electromagnetism, and relativity.

Momentum vectors play a significant role in describing complex systems, such as collisions and exchanges of momentum between objects. When two objects collide, their momentum vectors can be used to visualize the resultant motion. Furthermore, the conservation of momentum dictates that momentum vectors remain constant in isolated systems. This concept provides a powerful tool for understanding the motion of objects in diverse situations.

The momentum vector is typically represented using the symbol, p, with its direction aligned with the direction of the motion. Mathematically, the momentum p of an object can be calculated using the equation p = m × v, where m is the mass and v is the velocity of the object.
