... stay in motion. But just how much do moving objects wish to stay in motion? Does a 1 kg skate moving at 10 m/s “want” to stay in motion as much as a 10,000 kg truck moving at the same speed? To answer, think about which one would be harder to stop. Better yet, which one would you rather have approac ...

Momentum
... • When a dish falls, will the impulse be less if it lands on a carpet than if it lands on a hard ceramic tile floor ? • The impulse would be the same for either surface because there is the same momentum change for each. It is the force that is less for the impulse on the carpet because of the great ...

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.
