The term "power" has a very specific meaning in the study of mechanics. Power is defined as the amount of work performed per unit of time, and physicists measure it in joules per second, or watts. As a practical matter — and as we will use it here — power can be best understood as the ability to exert force rapidly. More terms now: Velocity is the speed of an object, the rate of change in its position. Acceleration is the rate of change of velocity, the increase (or decrease, known as deceleration) in the speed. For an object to change speed, to accelerate, force must be applied to it, since the nowfaster moving object has more kinetic energy. Strength is the physical ability to generate force. "Power" is the ability to generate that force rapidly. A more familiar term for this might be "quickness," especially when applied to movement of the body itself. For sports, just developing strength is not enough - you must also develop the ability to rapidly recruit the strength you build, so that you can accelerate better. A strong man might very well be able to apply enough force to a very heavy weight to get it moving, but a powerful man can get it moving more quickly. |
