Dimensions. 4.1 Newton's second law and momentum. Newton's second law states that the acceleration produced by a force on an object is directly proportional to the net force and inversely proportional to the mass of the object . . In classical mechanics, the momentum of a particle is defined as a product of its mass and its velocity, . . In an isolated system of particles, with no net force acting on the system, the total momentum of the system remains the same. However , we can see from a simple though experiment that the quantity . What was Angular Momentum Again?. If a particle is confined to going around a sphere:. At any instant the particle is on a particular circle. r. v. The particle is some distance from the origin, . r. Linear Momentum. Momentum is a measure of how hard it is to stop or turn a moving object.. p. = m. v. (single particle). P . = . Σ. p. i . (system of particles). Problem:. How fast must an electron move to have the same momentum as a proton moving at 300 m/s?. Mass energy equivalence. In quantum mechanics , we considered that kinetic energy could be increased only increasing by its velocity. But now dealing with relativistic mechanics we take mass variation into account.

The principle of relativity requires that . if the laws of physics are to be the same in every inertial reference frame, the quantities on both sides of an = sign must undergo the same Lorentz transformation so they stay equal. . Momentum = Mass x Velocity. p. =. mv. The SI unit for momentum is . kg·m. /s. Momentum and velocity are in the same . direction. Is a vector. Using the equation. p=. mv. At the same velocity, as mass increases – momentum increases. What is Momentum? Momentum may be defined by its equation: Momentum is a quantity defined as the product of the mass and velocity of an object. Unit of Momentum The equation illustrates that momentum is directly proportional to an object’s mass and the object’s velocity. You can calculate the momentum of a particle and the impulse of a force. The momentum of a body of mass . m. which is moving with velocity . v. is given by . mv. If the mass is in kg and the velocity is in ms.
