Study Guide for Momentum and Impulse test Chap 6

Here is a list of topics for the Chap 6 Test

1.  calculate linear momentum given m and v  and understand that negative veloccity defines opposite direction  P = mv

2.   Understand the Impulse momentum equation   M delta V = f delta T  Impulse is f de;ta t measured in Nxsec  and change in momentum is measured in Kg X m / sec  Be able to calculate any one quantity given the three

3.  Calculate stopping distance  as in Sample problem C pg 202 text  You must remember the four equations of motion

4.  Know the equations  for conservation of Momentum and kinetic energy

5.  Know the difference between an elastic and inelastic collision and what is conserved in each type


6.  Solve for a final velocity in an inelastic collision  (practice E pg 214)

7.  Solve for a final velocity in an elastic collision  (sample G pg 218)

8.  Be able to calculate the change in KE for a collision and interpret results.  Ex if delta KE = O, then KE was conserved and this was perfectly elastic.  If KE is not zero, energy was lost as nonmechanical energy like heat, sound.
