Question

Explain the relation between Joule and Erg.​

Answer 1

==> One erg of energy is the amount of work done when one dyne of force acts through a distance of one centimeter.

==> One Joule of energy is the amount of work done when one Newton of force (100,000 dynes) acts through a distance of one meter (100 centimeters).

==> That makes one Joule the same amount of energy as 10 million (10⁷) dynes.

Answer 2

Both erg and Joule are units of Energy in the CGS and S.I system respectively.

Joule and erg can also be written as (kg m2/s2) and (g cm2/s2) respectively.

Step-by-step explanation:

1 Joule = 107 erg ⇒ 107 kg m2/s2.
