Document Summary
Explanation: c, and the strength of gravity and the height: what are the units of energy and work, n, nkg, nm2. Outside of physics, don"t transform it to a useful form. Energy gained or lost from 1 = energy lost or gained from 2 and 3. Do work to pump from one form of energy to another. Energy is never created nor destroyed, just transferred. Amount of work done = amount of energy converted. = force applied x distance moved in direction of force. Example: you give your friend money- she has more and you have exactly that amount less. There is still the same amount money in the world. Money is money no matter the form (bills, coins, etc. ) Spring potential = x spring constant x (amount stretched)2. Gravitational potential = mass x g x height. Thermal = constant x temperature (in some cases) Push frictionless cart up 2m ramp with constant force at constant velocity.
