2.  In sports when player has a lot of momentum, what we mean, that it will be hard to stop them.  In Physics momentum refers to the quantity of motion that an object has.  A sports team that is on the move has the momentum. If an object is in motion (on the move) then it has momentum.

3.  Momentum can simply be defined as mass in motion  Since every object has mass, if it is in motion it has momentum  How do we measure momentum? p=mvp=mv

4.  In the above equation p stands for momentum, m stands for mass, and v stands for velocity.  The amount of momentum something has is dependant upon two variables; mass and velocity  Mass = how much stuff is moving  Velocity = how fast the stuff is moving

5.  Remember, in this equation both mass and velocity are directly proportional to momentum!  Directly proportional means if mass or velocity increase our momentum will increase by the same factor.  The units of measure we use for momentum are simple; we use kg(m)/s

6.  It is important to understand and remember that momentum is a vector quantity.  Vector quantities as you should recall have both magnitude and direction.  We get our magnitude from the equation p=mv  We get our direction from the direction the object is moving

7.  The Quarterback is traveling north towards the end zone at 2m/s and has a mass of 100kg. What is his momentum?  Use your colored pencils and the equation p=mv to solve!

8.  The Quarterback is traveling north towards the end zone at 2m/s and has a mass of 100kg. What is his momentum?  Mass of the quarter back = 100kg  Velocity of the quarter back = 2m/s  Momentum=mass(velocity)  ?=100kg(2m/s)  200kg(m)/s northward

9.  If something has a large mass it is going to have a lot of momentum.  If something has a lot of velocity it will also have a lot of momentum because both velocity and mass are directly proportional to an objects momentum.

10.  What is an objects momentum if that object is at rest?  In this photo the car is at rest; which means it is not moving and has a velocity of 0m/s  Momentum MUST be 0kg(m)/s as well.

11.  1. Determine the momentum of a... ◦ a. 60-kg halfback moving eastward at 9 m/s. ◦ b. 1000-kg car moving northward at 20 m/s. ◦ c. 40-kg freshman moving southward at 2 m/s.
