... Although the speed varies linearly with time, KE is the square of the speed, so it should be a parabola, which rules out graph B. In graph D the PE is decreasing quickly at first and then more slowly while in graph A the PE is decreasing slowly then quickly. Since the ball speeds up as it approaches ...

In these cases if the initial and final masses and velocities can be measured and the time of contact determined, the averag ...

Quantum vacuum thruster
A quantum vacuum plasma thruster (or Q-thruster) is a proposed type of spacecraft thruster that would work in part by acting on the virtual particles produced by quantum vacuum fluctuations. This was proposed as a possible model for an engine that could produce thrust without carrying its own propellant. Some physicists working with microwave resonant cavity thrusters think that they might be the first examples of such an engine.
