Force Flashcards
1
Q
What would be an elastic collision?
A
Collision by which there isn´t a net loss in KE in the system as a result of the collision. Momentum and KE are conserved.
2
Q
What would make a collision elastic in a container full of gas?
A
Wall rigid and particles points. (Nowhere for a particle´s KE to GO)
3
Q
Calculate velocity changes.
A
−mx
to +mvx
4
Q
Calculate change in momentum.
A
Δmv=+mvx−(−mvx)=2mvx
5
Q
K =12mv¯2=3/2kBT.
A
This is the average kinetic energy of a molecule.
6
Q
AVerage kinetic energy of a molecule is directly proportional to its __________________________
A
Absolute temperature.
