course Phys 202 As the partiles collide, they move off in a v shaped pattern. When they collide, the KEx goes up and the KEy goes down. The system is more organized after a cople of minutes.The KEx would be greater but only by a little if the KE were averaged for 100 years.The average KEx after 33 times is 550.76. THe KEy is 511.37. The particles are always moving in the x direction but mostly move in the y only after they collide.I believe tht the differance between the two averages are significant in that they are close to each other.
