Actually, it does both depending on how you use them. The sails can move so a person sailing a boat can catch the wind by how they move the sail or they can also stop the boat by the movement of a sail or lowering the sail.
Yes, because if the sale is bigger it will catch more wind wich will make the boat move faster. If the sale is smaller it will catch less wind and it will go slower.
Forces are the only thing that can do that.
faster
They move faster.
faster. and matter then would move slower
Energy
With the help of heating the movement is faster.
Overdrive lets the engine run slower at highway speeds. This saves on gas.
No, as heat is lost molecules move slower.

Slower or faster than what? - When the Earth is nearer the Sun (periapsis), it moves faster than when it is farther away from the Sun (apapsis).
the water molecules move away, e.g. evaporate
