What is the difference between strength and power???
Good question - and rarely one that is understood. Strength is defined as the ability to produce force. Whereas, power refers to the rate at which Work (i.e., Force x Distance) is performed at any instant. To improve power, trainees usually try to increase the velocity of the movement. Whereas strength is increased just by trying to overcome resistance, even if it is slow.
Even though many trainees think they will become faster just by increasing maximal strength levels, it is not always the case. Therefore, trainees training for power are usually attempting to overcome a resistance quickly (usually with a lesser load).
Now you know why I often write about Explosive Strength since increasing it will increase your power (which is lacking in many trainees).
This is a very basic definition/explanation, but I hope it helps you understand the differences.
