what is the formula for average kinetic energy. The formula for kinetic energy of a point mass or rigid body moving at non-relativistic speeds speeds very less than speed of light is the following. But we take the average of the velocities of all molecules to make it convenient for study.

The Kinetic energy is articulated in Kgm 2 s 2. At wall 1 it collides and the gains momentum mv x. When talking about bullet kinetic energy the word muzzle energy is often brought up.
Some molecules will be traveling faster and some more slowly.
The formula for kinetic energy is KE. Kinetic Energy KE ½ M V2 Here M is the mass of the point mass in Kg or rigid body and V is the velocity msec at which it is moving. Similarly the molecules collide wall 2 reversing the momentum ie -mv x. Note that the average kinetic energy for molecules is not the same as the average energyfor purely random energies under the Boltzmann distribution which is EavgkT.
