Q:Define momentum

  A:the product of an object's mass and velocity.

Q:Define Conservation of momentum

     A:The rule that in the absence of outside forces the total momentum of objects that interact

Q:Identify the formula for momentum

      A: (mass)(velocity)=momentum

Q:Find why the letter P represents the word momentum in the formula

      A: They are thinking that it came from the Latin word "petere" which means "go towards".They couldn't use "m" since it was already used for mass.

Q:Explain how a heavy moving van have the same momentum as a small motercycle

   A:It could have the same mass or velocity

Q:Explain the diffrence between a "sticky"collision and "non-sticky" collision

    A:When it is a sticky collision only one object has momentum and the other one rests at zero but when it is a "non-sticky" collision tboth of the objects have momentum

Q:Find a picture on the internet to support the definition of an elastic collision and label

     A:

When the player hits the ball with the paddle it would hits the table and bounce back it shows elastic collision

Q:find a picture to support the definition of inelsastic collision and label

   A:

when the book hits the ground it will loose some energy by mechanical enegry

Q:It at type of collision would you think throwing a piece of clay onto the ground would be and why?
  A:It would be inelastic collision because it would not have the same energy once it was in the air

Q:What is angular momentum? what dose it have to do with outer space?

   A:It is a measure of the amount of rotation an object has.It helps us to see how much the world has rotated.
