chemical potential energy, thermal energy, electrical energy, sound energy

Explanation:

the coal is chemical potential energy because it is just sitting there, the coal fueled power plant is thermal energy because it is using the heat from the coal to work the power plant, that is then turned into electrical energy, which then goes to the radio which displays sound energy

there is none because earth is stationary and flat.

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
