Exit Card: Conservation of Momentum (The Mechanical Universe) Name: ___________________________ ( /7) 1.) Name a game that demonstrates the conservation of momentum very well. _______________________ 2.) Momentum is the physics word for ______________ times ________________. 3.) Momentum is always ____________________________, or p1 + p2 = _________________. This is the Law of Conservation of Momentum. 4.) The point in an object where physicists assume that all of the object’s mass is concentrated is called the _____________________________________. 5.) When two billiard balls collide, they will exit the collision site with velocity vectors that are _______________________________ to each other. This is true as long as there is no ______________ or “English” on the balls AND as long as the collision is not ____________________.
