I guess I'm getting old and dumb but I'm having trouble with a basic physics concept, I'm sure you can explain it...
Why is kinetic energy 1/2mV^2 and not mV?
***** Example of my confusion no1.
Suppose person A has a mass of 1 and a velocity of 10 (on ice skates).
Momentum = mV =...
Why are we not able to capture and store light between two mirrors? I'm going to take a guess at the answer but I'd like to hear from someone who knows for sure...
I'm wondering if you actually can for a small amount of time, but the inefficiencies of an imperfect mirror cause some light to be...
