Answer 1

Simply energy is the ability to do work.

Energy is the capacity of a physical system to perform work. Energy exists in several forms such as heat , kinetic or mechanical energy, light, potential energy , electrical, or other forms.

1. coal, geothermal energy,
2. wind energy,
3. biomass,
4. petrol,
5. nuclear energy, etc.

Energy is classified into various types based on sustainability as renewable sources of energy and non-renewable sources of energy.

Step-by-step explanation:

`p = (w)/(t) \\ where \: \: w = workdone \\ \: \: \: \: \: \: \: \: t = time \: taken`

`kinetic \: energy(k.e) = (1)/(2) {mv}^(2)`

`potential \: energy \: = \: mgh`
