Momentum: Conservation of Momentum
State the Law of Conservation of Momentum.

 
 

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?
