Power is the ability to act fast against resistance — a combination of strength and speed — seen in shot put, long jump and a karate kick. Balance is the ability to maintain equilibrium while moving (dynamic balance) or stationary (static balance).

Speed is the ability to perform a movement in the shortest possible time — the minimum time to complete a task, as in a 100m/200m sprint or ice hockey. Agility is the ability to change the body's direction rapidly and accurately — itself a COMBINATION of speed, balance, power and coordination — seen in rugby, football and hockey.
