Dielectrics
... So the potential energy stored in the capacitor increases. Where does the energy come from? The simple answer is the battery. Thus we see the use of a dielectric in a circuit: it increases the stored energy in the capacitor. Also, it keeps the plates from sticking together due to coulomb attraction! ...

... III. If two bodies exert forces on each other, these forces are equal in magnitude and opposite in direction. The First Law would be meaningless without the concept of force, but it conveys a precise meaning for the concept of a “zero net force”. This tendency for a body to remain in its initial st ...

Woodward effect
The Woodward effect, also referred to as a Mach effect, one of at least three predicted Mach effects, is part of a hypothesis proposed by James F. Woodward in 1990.The hypothesis states that transient mass fluctuations arise in any object that absorbs internal energy while undergoing a proper acceleration. Harnessing this effect could generate a thrust, which Woodward and others claim to measure in various experiments. If proven to exist, the Woodward effect could be used in the design of spacecraft engines of a field propulsion engine that would not have to expel matter to accelerate. Such an engine, called a Mach effect thruster (MET), would be a breakthrough in space travel. So far, no conclusive proof of the existence of this effect has been presented. Experiments to confirm and utilize this effect by Woodward and others continue.
