Raising a mass of m = 5 kg by a height of h = 300 m under gravitational acceleration g = 9.8 m/s^2 represents an increase in gravitational potential energy of E = mgh = 14700 joules.
Power is the movement of energy over time, measurable in joules per second, or watts. Moving 14700 joules in 1 hour = 3600 seconds represents 14700 J / 3600 s = 4 watts of power.
- pjs_ 5y agoIf your body was perfectly efficient at converting calories into gravitational potential energy, the calories in a single can of coke would be enough to carry you 1km into space
- mwint 5y agoIs there a rule of thumb for the true efficiency of that calculation? I.e if I drink one can of coke, how far can I climb a ladder on the energy I metabolized from it?
