... This is actually reasonable. The area on the top of the piston doesn’t change, so the force exerted on it by the atmosphere is constant. When the piston rises to some position, the force pushing down is still the same, so the force inside pushing up must be the same as well. Since this force comes f ...

Conservation of Energy
... In an ideal situation this transfer of energy would be perfect and complete, but when was the last time you remember our universe being perfect…? This leads us to the second idea… 2. “In any energy conversion, there will always be some waste energy released as heat into the surrounding environment.” ...

... For a closed path, the total work done by a non-conservative force is NOT ZERO - as it is for a conservative force. For instance, a frictional force would oppose the motion and “slow” the car down. Unlike gravity, friction would do negative work on the car through out the entire trip, on both the up ...
