How much joules in mgh
Web3 MWh to joule = 10800000000 joule. 4 MWh to joule = 14400000000 joule. 5 MWh to … WebSo the initial energy is going to be equal to 100 joules. That's cause this is 0 and this is 100. So the initial energy is 100 joules. At this point right here, what's the potential energy? Well we're 5 meters up, so mass times gravity times height. Mass is 1, times gravity, 10 meters per second squared. Times height, times 5. So it's 50 joules.

WebIn classical mechanics, kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per … WebDec 6, 2024 · The first step is to set the equations for gravitational potential energy and work equal to each other and solve for force. W=PE=Fd=mgh \implies F=\frac {mgh} {d} W = PE = F d = mgh F = dmgh. The second and final step is to plug the values from the problem into the equation for force. Remember to use meters, not centimeters, for all distances.
