Heavy Cart Crashes into a Light One

Here is a video clip of a cart moving in from the right, that will collide with the cart which is sitting at the middle of the track. The cart moving in from the right is heavier than the cart in the middle. Watch what happens. This is like a truck colliding with a scooter.

You can see that the heavy cart collides with, and pushes the light cart towards the left. In physics, we say the heavy carts transfers momentum to the light cart.

Also notice what happens to the carts after the collision. Because the heavy cart is heavier than the light cart, the heavy cart "plows through" the collision. It not only sends the light cart flying away but is able to keep on going in the direction from which it came. Truck vs. Scooter!
