Consider the description of the two soccer
balls in the text and the data in Table 6-1.
a. What characteristics are noted in the table for each soccer ball?
b. Do any of these characteristics change
after the collision? Which?
c. What is the sum of the momenta of the
two balls before they collide?
d. What is the sum of the momenta of the
two balls after they collide?
e. How much has the momentum changed for
ball “A”? Did it gain or lose?
f. How much has the momentum changed for
ball “B”? Did it gain or lose?
g. Account for the changes in momentum?
Did they result from changes in mass or velocity?
What is an elastic collision?
What is an inelastic collision?
What is the difference between an elastic
and inelastic collision?
