THIS IS THE EXPERIMENT: The students, working in pairs, will obtain ten sealed vials. DO NOT OPEN THE VIALS! Having the vials preloaded saves chemicals, time, and minimizes the possibility of exposure. These vials are labeled with their contents. Nine of the vials will contain knowns, while the last vial will be an unknown. This unknown will be one of the previous nine. Zero the analytical balance, then place the magnet on the balance and record its apparent mass; the...

Background Info: In this experiment you will observe and analyze elastic and inelastic collisions in one dimension and in two dimensions. You will measure the final momentum of a system after it explodes. You will see how both kinds of collision affect the kinetic energy of a system that consists of two frictionless carts. You will determine the momentum of two carts after they collide when one cart is initially stationary. You will analyze the results qualitatively as well as...
