Question

Non relativistic method of calculating electron velocity

Answer 1

Kinetic energy is the energy a body has due to its motion. The formula for calculating the kinetic energy of a body (in the non-relativistic regime) is pretty simple:



The SI units of energy are Joules:



Answer 2

Kinetic energy is the energy a body has due to its motion.The SI units of energy are Joules.Sometimes, people use other units to describe energy. For example, if one measures mass in grams, distance in centimeters, and time in seconds -- the cgs system, which is sometimes used by astronomers -- then the units of energy are ergs.

High-energy physicists often use a unit of energy called the electron-Volt, or eV. If you let an electron accelerate across an electric potential of 1 Volt, then the kinetic energy it gains by the end of its journey is one eV.
