ok lets say i have a box thats 50kg. its 2 meters high. so i plug and chug those into the equation and i get 980 joules. 50*9.8*2=980. ok sooo this box has 980 joules potenetial work. the question i have is since 1 joule equals a watt would it be safe to say that what we have is almost a kilowatt.(considering if you could convert with 100% efficiency which i know you cant) but would it convert like that or is there something im missing? also the total work that could be done is an amount of energy. and watts are usually defined as a rate soooo how would that convert. thx in advance.
