Deflection (physics)
From Wikipedia, the free encyclopedia
Deflection occurs when an object hits a plane surface
In physics deflection is the event where an object collides and bounces against a plane surface.
Magnetic deflection refers to Lorentz forces acting upon a charged particle moving in a magnetic field.
An object's deflective efficiency can never equal or surpass 100%. For example, a mirror will never reflect exactly the same amount of light cast upon it. Also, a ball in free-fall (meaning no forces are acting on it other than gravity), upon hitting the ground, will never bounce back up to the spot where it first started to descend. This is due to the Laws of Thermodynamics, which state that, in every action, some energy being used in that action escapes into the environment.
