http://hyperphysics.phy-astr.gsu.edu/hbase/quantum/debrog2.html WebHere's a key point from physics: mv is a particle's momentum. The standard symbol for momentum is p: 2Em = p 2. p = √(2Em) Now comes the second equation. It is one of two related equations called the de Broglie equations. You can read more about de Broglie's work here. He received the 1929 Nobel Prize in Physics for this work.

1. If the body is a massless particle (m0 = 0), then (1) reduces to E = pc. For photons, this is the relation, discovered in 19th century classical electromagnetism, between radiant momentum (causing radiation pressure) and radiant energy. 2. If the body's speed v is much less than c, then (1) reduces to E = 1/2m0v + m0c ; that is, the body's total energy is simply its classical kinetic energy (1/2m0v ) plus its rest energy.

WebKinetic energy tells you how long of a distance you would need to apply a given force F to an object to make it stop. Momentum tells you how long of a time you would need to apply a given force F to an object to make it stop. Imagine you have a car moving at speed v, and it brakes and comes to a stop after a distance d and time t. WebExperiment I. Momentum-Energy Conservation February 21, 2024. Objective: The objectives for this experiment were to study the idea of momentum as well as its uses in collisions. The other objective was to verify the conservation of momentum and energy in collisions.
