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.
How do you calculate joules when temperature changes?
WebIn order to answer the question the first thing to do is divide the result by watts (remember that 1 watt is 1 joule per second): 9 x 10 16 J / 100 W = 9 x 10 14 seconds That's a lot of seconds, but how long is that in years? A year (365.25 days) is 31,557,600 seconds, so: 9 x 10 14 seconds / 31,557,600 seconds = 28,519,279 years WebMar 20, 2024 · Let’s solve an example; Find the potential energy when the mass is 12 with a height of 24 and acceleration due to gravity of 9.8. ...
