I am not sure if I'm entering the physics question correctly. For example, if I enter this problem: An elevator is able to raise 9800 N to a height of 37 m in 14 s. What is the work done and what is the power output?
If you have the formulas, it can solve them for you:
f = Quantity[9800, "Newtons"] h = Quantity[37, "Meters"] t = Quantity[14, "Seconds"] w = UnitConvert[f*h, "Joules"] p = UnitConvert[w/t, "Watts"]
