"WebFirstly, instantaneous power is equal to F · v. If we said that F = m · a, and plug that into the instantaneous power, then we would have P = m · a · v. So now we can see that for the power, the mass does matter. Then, the instantaneous speed is a magnitude that is constant by the simple meaning that is in an infinitesimal time interval.

WebHow do I calculate watt hours (Wh)? To work out the Wh take the watts (W) of the appliance and multiply this with the hours used on the average day. This will give you the Wh consumed in your caravan/RV per day. Calculation: Appliance watts x hours used per day = daily watt hours consumption . Example 1 - portable fan WebPower is the rate at which work is done. In this case, rate means per unit of time. Power is calculated by dividing the work done by the time it took to do the work. P = W t Let’s consider an example that can help illustrate the differences among work, force, and power.

WebJul 6, 2014 · would it be correct to calculate work as the change in PE for the weight: W = ΔPE = (m) (g) (h) = (225 lb) (32.17) (2 ft) It would be correct, but the way you did it is incorrect. Remember: 225 lb is not the mass of the object, it's the weight of the object. So ΔGPE would just be 225lb*2ft Last edited: Jul 5, 2014 Jul 5, 2014 #3 Dale Mentor WebTo calculate time, power, or work, follow the steps below.
