1. Momentum:

2. Momentum is a vector! Momentum: Measure of mass in Motion
Momentum = mass * Velocity Or
P= MV
Standard Unit : Kg * m/s
Momentum is a vector!

3. 3 Kg * m/s .25 Kg * m/s A 3 kg ball is moving with a
velocity of 1 m/s. What is the
ball’s momentum?
3 Kg * m/s
What is the momentum of a
.5kg ball moving .5 m/s?
.25 Kg * m/s

4. Conservation of Momentum:
Collision: Two objects that exchange
energy and Momentum
Conservation of Momentum:
total momentum of a system of objects
does not change, as long as no outside
force acts on the system

5. How does increasing the speed of an
Object change its Momentum?
A car and a Truck are traveling at the
Same speed. Which has more
momentum? Why
Give two examples showing the
Conservation of Momentum. Give one
Example where momentum is not
Conserved.

6. A performing dolphin speeds through
water and hits a rubber ball originally
at rest. Describe what happens to the
velocities of the ball and dolphin?
A moving train car bumps into another
train car with the same mass. After the
collision, the two cars are coupled
together and move off. How does the
final velocity of the two trains car
change?
