When any object with mass moves, no matter at what speed, its mass increases. The faster it moves, the faster its mass increases. And the closer to the speed of light it moves, the closer to infinity its mass grows.
They speed up and moves faster and faster.
"Fast" is an adjective. It describes the speed at which something moves or happens.

You can induce a larger electric current by either increasing the strength of the magnetic field or increasing the speed at which the magnet moves through the coil of wires. Both of these factors contribute to the rate at which magnetic flux changes, resulting in a larger induced current in the coil.
It isn't quite clear what you mean with "direct speed". Any time an object moves, it has speed.
