Momentum

Today in class we expanded on momentum.  As of right now my picture isn't cooperating and attaching in this blog post but I will eventually get it up.  Anyways, the picture is of Capri sitting on the round surface with the leaf blower thing attached.  In this picture she is throwing a medicine ball to someone and when she does the round surface that she is on moves back.  This is very similar to the cart air lab that we did yesterday.  The heavier the mass is, when colliding will push the lighter object and the speed/momentum will transfer.  Today when she threw it the same force she used to throw the ball acted the exact same way onto her.  The object was also frictionless so we could see clearly what happens.  We learned an equation today that states that the initial equals the final.  So everything on both sides of the equal sign are the same (equal to each other) which is why when Capri threw the ball she went backwards also.
