Question

A kinetic energy transer was observed through a single collision. The information provided in the collision simulation was as follows:

Object #1 (before collision)

m = 2 kg and K=4.0J

Object #1 (after collision)

m=2 kg and K = 11.1J

Object #2 (before collision)

m = 1kg and K = 18.0 J

Object #2 (after collision)

m = 1kg and K = 10.9 J

Calculate the difference in kinetic energy between the objects before and after the collision. Report these numbers.
How are your observations related to temperature?

Explanation / Answer

Here ,

difference in kinetic energy = final kinetic energy - final kinetic energy

difference in kinetic energy = (final KE of object 1 + final KE of object 2 ) - (initial KE of object 1 + initial KE of object 2 )

difference in kinetic energy = (11.1 + 10.9) - (4 + 18)

difference in kinetic energy = 0 J

the difference in kinetic energy is 0 J

the difference in kinetic energy between the objects before and after the collision is 0 J .

as the kinetic energy is 0 J

the final temperature is same as the initial temperature .
