Momentum - the product of an object’s mass and velocity. The more momentum an object has, the harder (more force) to bring it to rest.
p - momentum (kg m/s)
m - mass (kg)
v - velocity (m/s)
2
Multiple Choice
What is p in equation p = mv
power
momentum
mass
velocity
3
Total Momentum
Each object in the system has its own momentum, the sum of each object’s momentum is equal to the total momentum of the system
4
Open Ended
How would you find total momentum of the system?
5
Conservation of momentum
Conservation of Momentum:
The total momentum in a system will remain the same when two objects interact as long as there is no outside forces acting on the system.
The change in momentum of one object is balanced by the change in momentum of the other object so the total momentum remains constant.
mA.vAi + mB.vBi = mA.vAf + mB.vBf
6
Multiple Choice
Total momentum of the system is always conserved
True
False
7
Multiple Choice
Momentum of each object is always conserved
True
False
8
Open Ended
Explain all the variables in equation

Multiple Choice
Read the following and discuss with your partner. If your partner is not up to that slide then wait for your partner to finish previous slides. Discuss it with your partner and select a skill below that you need for this concept. Select all that apply.
Mass and Velocity are the two variables that determine the amount of momentum. So large objects moving fast have the most momentum.
Be able to calculate the momentum of an object using the equation p = mv
Be able to identify the objects interacting in a system
1)Be able to calculate the total momentum of the objects in a system ptotal = pA + pB
2)Apply the conservation of momentum principle to calculate velocity of objects before or after collisions.
Be able to calculate the change in momentum Δp = m Δv or Δp = pf - pi
Be able to calculate the impulse an object experiences Impulse = Ft
