Momentum
By: Kara P.  

    Momentum  is the product  of an object's mass and velocity. Law of conservation of Momentum states that, in the absence of outside forces like friction,the total momentum of objects that interact does not change. You calculate momentum by momentum=mass x velocity or p=m x v. The letter is p represents momentum because of physics. A sticky collision is when two objects with the same mass share momentum. A non-sticky collision is when two objects with the same mass don't share momentum. Throwing a peice of clay on the ground would be a sticky collision because they shared the same mass and the momentum. Angular momentum is when an object spins around and around like a top instead of going straight. The earth spins around and around every day while orbiting the sun. #kettner #momentum
