course Phy 202 Referring to the below information from a previous submission... if we are in a situation without a gravitational field, what would be a quality of the blue particle to make it behave as it does in the program? Is that program written to assume we are in a gravitational field? What do you think are the average velocities of the 'red' and the 'blue' particles and what do you think it is about the 'blue' particle that makes is so? ......!!!!!!!!................................... RESPONSE --> I believe the blue particle to be heavier than the red particle because on average it moves much slower. At the top of the program, the first number is the red velocity (avg 5). The second number is the blue particle's velocity (averaged 1.5)

14:20:58 ** Student answer with good analogy: I did not actually measure the velocities. the red were much faster. I would assume that the blue particle has much more mass a high velocity impact from the other particles made very little change in the blue particles velocity. Similar to a bycycle running into a Mack Truck. INSTRUCTOR NOTE: : It turns out that average kinetic energies of red and blue particles are equal, but the greater mass of the blue particle implies that it needs less v to get the same KE (which is .5 mv^2) **

RESPONSE --> ok. the blue particle has more MASS, and therefore is heavier due to the greater effect of gravity upon this mass. That is the case only if the particle is in a gravitational field.
