You can calculate kilowatts from joules and seconds, but you can't convert joules to kilowatts, since joule and kilowatt units represent different quantities. Joules to kilowatts calculation formula The powerPin kilowatts (kW) is equal to the energyEin joules (J), divided by 1000 times the ...
How to convert energy in joules (J) to electric power in watts (W).You can calculate watts from joules and seconds, but you can't convert joules to watts, since joule and watt units represent different quantities.Joules to watts calculation formulaThe power P in watts (W) is equal to ...
Since the force required to lift it is equal to its weight, it follows that the gravitational potential energy is equal to its weight times the height to which it is lifted. PE = kg x 9.8 m/s2x m = joules.PE = lbs x ft = ft lb. What is the formula to calculate potential energy?
It was given in the problem that the mass of the sample is 2 kilograms, the amount of heat energy added to the sample is 1000 joules, and the temperature increase is 5 degrees centigrade. Step 2:Use the formula to calculate the specific heat of the substance. ...
Step 3: Solve for Energy Multiply ν Planck's constant, h, by ν to get the value of E. In this example: E=6.626×10−34×3×1014=1.988×10−19J Cite This Article MLA Beck, Kevin. "How To Calculate Hertz To Joules"sciencing.com, https://www.sciencing.com/calculate-hertz-joule...
Physics has a specific definition of work – work is done when a force moves an object over a distance. Work is related to energy. It's measured in joules in the SI system., which are also potential and kinetic energy units. To convert work into potential energy, you have to act ...
An equipotential is a path through space where the voltage is constant along that path – similar to electric field lines. Electric potential is in units of joules (energy) per coulomb (electric charge), so it describes the amount of energy exerted per unit of charge. We can also describe ...
will hold the rate at which energy is delivered or used (joules) during an amount of time (your step size, multiplied by the number of steps per RRA row). The rate at which energy is moved is called power. The next thing to determine is what you want to be able to monitor. Do yo...
Calculate the energy required to heat a 1.5-kg block of ice at -10 degrees Celsius to a cloud of water vapor at 120 degrees Celsius. Water's melting point is 0 degrees Celsius and its vaporization point is 100 degrees Celsius. The latent heat of fusion is 334,000 ...
