Summarize:

1. Toy car is going to get pushed and is exactly going to stop after hitting the marble (because of the string), the marble is being stopped by a small piece of wood.
2. Marble goes down and down through the cups.
3. Marble is led to the slide with the big ball.
4. Marble pushes big ball down.
5. Big ball hits easy button.
6. That was easy.

Energies:

1. When the car is pushed it gains potential energy hitting the marble.
2. Car’s energy transfers to kinetic when it hits the marble.\
3. Then marble goes down. Kinetic-Kinetic.
4. Then when it goes down the cups it gains potential energy. The combination of potential and kinetic energy is mechanical energy.
5. Then marble goes down the slide to mechanical to kinetic.
6. Then marble hits big ball transferring the kinetic energy.
7. Big ball with kinetic energy hits the easy button making sound energy.
