1. Momentum Chapter 2.3

2. Momentum, Mass, and Velocity
Momentum (p): the product of the mass and velocity of an object
The more momentum an object has the harder it is to stop or change its direction

3. Calculating Momentum
Momentum: Mass of an object multiplied by its velocity
P=M X V
Unit: kg*m/s

4. Law Conservation of Momentum
States that when any time objects collide, the total amount of momentum stays the same
When a moving object hits another object, some or all of the momentum of the first is transferred

5. Practice Problems Find the momentum of the different balls
m= .045 kg m=.168 kg m= .575 kg
V= 16 m/s upward v=3 m/s forward v= 9.2 m/s east
At a rodeo, a bucking bronco throws an 81 kg rider into the air at a velocity of 10 m/s upward. What is the riders momentum?
What is the velocity of a 55 kg skater who has a momentum of 440 kg×m/s forward?
