You can raise an object (potential energy), make it move (kinetic energy), or add heat to it (heat energy, a.k.a. thermal energy).

when you add thermal energy to matter, the matter starts moving faster.
when you add thermal energy to matter, the matter starts moving faster.
When you add thermal energy to matter, either the temperature will increase, or there will be a change in the state (phase) of matter, for example when ice melts.

They move faster.
heating it
Yes, particularly if you add thermal energy. At its least energetic, matter is in the solid state. Add some more energy, it transitions to the liquid state. Then more and it's a gas. Finally, at its most energetic, it is in the plasma state.
faster. and matter then would move slower
That depends a lot on how the particle was moving in the first place, and how the energy is added.
