| 1 | Spring Apart Carts |
Conservation of Linear Momentum
|
Two carts are fixed together with a spring in between them. The trigger is tripped and the spring pushes the carts apart. Different masses in the carts give different exit velocities. |

| 2 | Carts and medicine ball |
Mass and Momentum Transfer
|
Two people on roller carts throw a medicine ball to each other. |

| 3 | Collision Balls |
Collisons in 1D
|
One ball raised and let go on one end will give one ball launched out from the other. Try different numbers of balls. If it doesn't work well, there is probably an alignment problem. Make sure the threads are straight and the balls are in a perfect line. |
