Catalysts
Friction does not speed up an object; it creates drag and slows it down.
The electric motor could have more than one armature on the shaft, and these could be electrically coupled in series for slow speed and in parallel for high speed. (These alternative connections were known as "group down" and "group up", respectively.)
In the days when men rode horses, they would often say to a horse "get it up" meaning "speed up" or "take off". The word gidyap originates from this.
Warm up exercises and ATPase activity of myosin determines the speed of muscle contraction. Studies with less warm up show muscle twitching.
The slowest softball pitch is the change-up. It is used to trick the batter into swinging early. When pitchers have a good change up it can be used quite often with the same effect each time. Pitches can also be thrown off-speed, like an off-speed curve ball.
