What does the same amount of energy look like in different forms?

Question

Energy can be transferred from one form to another, but I’m not sure how to visualize what it looks like when this happens. For example, what would the kinetic energy of a moving car look like if all the energy (perfectly converted) was heat, sound, or light?

Answer 1

The energy of a car travelling at 100kmph is around 770kJ. That’s equivalent to the chemical energy of about 33 peanuts, or the radiation energy of sunlight shining on the car for 1/14th of a second. Or the energy to get a 2.25L bottle (like the big plastic coke bottles) of water from room temp to boiling.
