Moving Rulers Are Shorter – Length Contraction Example Problem

Relativity tells us moving objects will have different lengths in the direction of motion, depending on the frame of reference of the observer. This is known as length contraction. This type of problem can be reduced to two different frames of reference. One is the frame of reference where a […]


Momentum Example Problem 1

Conservation of Momentum Example Problem 2   Recently updated !

Momentum is a measurement of inertia in motion. When a mass has velocity, it has momentum. Momentum is calculated by the equation momentum = mass x velocity momentum = mv This conservation of momentum example problem illustrates the principle of conservation of momentum after a collision between two objects. Problem: […]
