A dynamical system in which repeated measurements on a single particle yield the same mean result as a single measurement of the whole ensemble is said to be ergodic. The ergodic theorem expresses a ...
Newton’s shell theorem asserts that the net gravitational force between a point particle and a sphere with uniform mass density is the same as the force in the situation where the sphere is replaced ...
If a particle has negative acceleration then it must be slowing down, right? Nope. Sorry. Try again. This is an extremely common misconception. This applet is intended to address this misconception ...
