This is a pitifully simplistic interrogatory, but here goes. Is this roughly how an AC circuit works?: An AC generator supplies an electron flow to start the circuit. These electrons then flow down a single wire to say a household fusebox/breaker. From there they flow to a wall plug and then...

If for every action there is an equal and opposite reaction, then how come net forces exist? Surely when a force is exerted on an object, an equal force must push back (reaction) in the opposite direction, therefore balancing the forces, creating no net force and thus no acceleration? How do...
