Web2 Answers. Sorted by: 3. Power is the amount of energy produced (or consumed) for unit of time. For exemple, Sun's reaction produces x MeV of energy per day. So, it's power is x ( 24 ∗ 60 ∗ 60) M e V s. Power = energy time (more precisely d P = d E d t) Share. Cite. WebTo learn how power is transferred in a vehicle, key terms (force, work, power, and energy) and the relationship between them need to be studied. Force. Simply defined, force is a push or pull interaction between objects. This interaction can occur when objects are in physical contact with one another or when there is an action at a distance ...
WebDifference Between Work and Power. Work is the amount of force required to move an object by applying outside force, while power is the degree at which work is done. Joule (J) is the SI unit of work, whereas Watt (W) is the SI unit of power. The work is denoted by the formula W = F.S; conversely, power is indicated by formula P = W/t.
WebJan 2, 2024 · The two measurements are connected through math. (“OH NO! MATH!” But I promise this math is easy to understand.) To get energy, you multiply power by time. For kWh, it is kWh(energy)= kW(power)*time (usually hours). To get power, you divide instead of multiply. You divide the energy by time. For kW, it is kW(power)= kWh(energy)/ time. example of a national businessWebNov 14, 2014 · Energy is what makes change happen and can be transferred form one object to another.
