Step 1. The first step is to drop the ball down the cardboard tube 

Step 2. The second step is the ball hits the first train 

Step 3. The third step is the first train hits the second train 

Step 4. The fourth step is the second train hits a domino making all the dominos fall 

Step 5. The fifth step is the dominos hit the ball over 

Step 6. The sixth and last step is the ball falls down the cardboard tube from the dominos and hits the play button on keyboard  

During the first step, the ball’s gravitational potential energy transforms into rotational kinetic energy as it rolls. A train’s potential energy is also present in the second and third steps until the ball touches train number 1. Train number 1 collides with train number 2, transforming both into kinetic energy. Step four shows the dominos as potential energy until the train hits them, when they become kinetic. Prior to it falling into a tube, the ball has potential energy as well as kinetic energy when it is knocked over by dominoes. In the sixth step, the laptop has electrical and thermal energy, and when the ball hits, it also has sound energy.

Keep in mind I had no help with the project so the filming is not the greatest.
