Can anyone mention some of the work-energy formulas used in M1 - CIE AS Level.
I know of some of them:
work done = change in kinetic energy + work done against resistance
loss in GPE - gain in kinetic energy = work done against resistance
But I've seen some work-energy formulas in the marking schemes that I'd never come across, such as:
total work done = gain in GPE + work done against resistance
gain in GPE = work done by driving force + loss in KE - work done against resistances
total work done = loss in GPE - gain in KE
Can anyone explain these to me, and please let me know about any further variations of these.
Thanks loads!
