Special Theory of Relativity
... "It followed from the special theory of relativity that mass and energy are both but different manifestations of the same thing -- a somewhat unfamiliar conception for the average mind. Furthermore, the equation E is equal to m c-squared, in which energy is put equal to mass, multiplied by the squar ...

... ΣFx = m v²/r = T sinθ ΣFy = m g = T cosθ In the example these two equations are divided, but can just as easily solve for T and substitute into the other equation to result in tanθ = v²/ rg; where r = L sinθ v = (L g sinθ tanθ)½ Cup Supplying Centripetal Force on the water (horizontal plane) ...

Uniform Circular Motion
... Can the velocity be accelerated even though it has constant speed? Yes, because the velocity may change due to direction. If direction changes and velocity changes then an object can accelerate. ...

... 1. A bullet with a mass of 20.0 g and a speed of 960 m/s strikes a block of wood of mass 4.50 kg resting on a horizontal surface. The bullet gets embedded in the block. The speed of the block immediately after the collision A) cannot be found because we don't know whether the surface is frictionless ...
