Okay, a slice of pizza contains 290 calories, which is about 1 ,200 kilojoules.
00:06
So that's our energy.
00:12
1 ,200 kilojoules or 1 .2 million joules, right? so there's our conversion from kilojoules to joules.
00:30
If you burn your pizza, it has fuel to power an oven with a 1 ,000 watt.
00:36
So that's power.
00:38
So the power output is 1 ,000 watts.
00:43
Or 1 ,000 joules per second, right? that's what a watt is, a jewel per second.
00:50
How long would one slice power the oven? so i can kind of see from the units here, we could say power is equal to energy per time, right? so power is joules per second, energy is jewels, and then time is seconds...
