The average kinetic energy can be calculated through several different methods. If provided with temperature, it can be determined using the equation KE = (3/2)RT. Alternatively, if given velocity, the average kinetic energy can be found using the equation KE = (1/2)mv^2.

In KE = (3/2)RT: KE stands for the average kinetic energy of particles in a system. R represents the gas constant (ideal gas constant: 8.314 J/(mol*K) or 0.0821 L·atm/(mol·K)). T represents the temperature in Kelvin (K). In KE = (1/2)mv^2: KE still represents the average kinetic energy of particles in a system. m stands for the mass of the particle v stands for the velocity of the particle.
