Question

Define the following terms 1 Joule 1 erg​

Answer 1

Joule, unit of work or energy in the International System of Units (SI); it is equal to the work done by a force of one newton acting through one metre.

An erg is the amount of work done by a force of one dyne exerted for a distance of one centimetre. In the CGS base units, it is equal to one gram centimetre-squared per second-squared (g⋅cm2/s2). It is thus equal to 10−7 joules or 100 nanojoules (nJ) in SI units.
