Question 3
a) My predictions were that the momentum of the system will be conserved. The result
found agree with my predictions. This is because before and after collision, the
momentum was the same. When the momentum is conserved, the total momentum of the
two objects before the collision is equal to the total momentum of the two objects after
the collision, which is not the case in our system.
b) The final velocities of IOLabs A and B agree with my prediction. The measured values
are what is needed for momentum to be conserved because they represent an elastic
collision. The results depict that the momentum lost by A is equal to the momentum
gained by B.
