Power to me "now" is being able to walk away from an argument without needing to always have the last word. I'm powerful 73% of the time. The other "something" percent of the time .. not so much. Math is not one of my powers :/
Depends. Power can be expressed multiple ways.It can be a function of distance and express the rate of energy transferred over a distance. It can be expressed as the rate of force at particular velocity. It's the amount of energy transferred over a time.
