Question

define energy and state it's CGS and SI units​

Answer 1

Answer:

The SI unit for energy is the Joule, or J. 1 J = 1 kg·m2/s2. The cgs unit forenergy is the erg. ... [Other commonunits for energy include the electron volt: 1 eV = 1.602 × 10−19 J, the calorie and the Calorie. The calorie is a very seldom used unit, 1 calorie = 4.184 J.

Answer 2

In physics, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed. 

The SI unit for energy is the Joule, or J. 1 J = 1 kg·m2/s2. The cgs unit for energy is the erg. ... ergs are a lot smaller than Joules; 107 ergs = 1 J. [Other common units for energy include the electron volt: 1 eV = 1.602 × 10−19 J, the calorie and the Calorie.
