Question

A kinetic transfer of energy is observed through a simulation of red atoms and blue atoms in real life. Red atoms begin on the left side of an enclosure and blue begin on the right side of enclosure. Below are the numbers observed before and after the collision. Calculate the difference in kinetic energy between the objects before and after the collision. Report these numbers.
How are your observations related to temperature?

BEFORE: K (red) = 11J     K (blue) = 3J

AFTER: K (red) = 7J         K (blue) = 7J

*Note as the atoms came closer and closer together the numbers on the graph read 10(red)/4 (blue), 9 (red)/5 (blue, 8 (red)/6 (blue), and then the final numbers 7 (red)/7 (blue)

Explanation / Answer

Are you just asking to calculate the difference in Kinetic energy.
Isn't that very simple.

For Red:
Initial KE =11 J
Final KE = 7 J
Difference in KE = 11-7 = 4J

For Blue:
Initial KE =3 J
Final KE = 7 J
Difference in KE = 3-7 = -4J = 4 J (in magnitude)

Net change in KE = 0
