Answer:

The capacity of performing any activity or work is termed energy.

Ans: The SI unit of energy is Joule and 

The CGS unit of energy is erg. 

So the relationship between Joule and Erg is –

1 Joule of Energy = 1 Newton X 1 metre

1 Erg = 1 dyne X 1 cm

1 Joule = 1 Newton X 1 metre

1 Joule = 105 dynes X 10² cm                                        [Where, 1 Newton = 105  dynes and 1 metre = 10² cm]

1 Joule = 107 Erg or 10000000 Erg

Therefore, 1 Joule is equal to 10000000 Erg
