A: Speakers emit sound, vibrating the ball off of it.
B: Ball falls down board and through funnel.
C: Elastic spring is pushed by the ball, and launches a toy car down a track.
D: Car knocks over dominos.
E: Domino hits chopstick to release a ball. The ball rolls down the track and hits another chopstick releasing another ball, and then hits another chopstick releasing another ball.
F: Last ball knocks over tower holding ball from rolling, then the ball is released and falls down hill.
G: Ball hits dominos and dominos hit box of cards.
H: Box hits chopstick and pushes up against a tape measure. Tape measure releases and launches back up to the body of the tape measure.
I: Tape measure falls hitting toilet paper roll into garbage.
Forms of Energy:
When radio waves and micro waves are given off of the phone, radiant energy is used. Electrical energy is used to produce sound in the speaker. Sound energy is emitted by the speaker. The ball is at an elevated point and therefor has gravitational energy. The ball rolls down the board using mechanical energy. The HotWheels track has a stretched elastic with elastic energy that slingshots the toy car forward. Mechanical, gravitational, and elastic energy are used throughout the rest of the machine.
Radio waves and micro waves are given off by the phone to the speaker (radiation), the speaker uses electricity to produce the sound. The sound vibrates the ball and pushes it off. The ball falls from a height using gravitational energy and then rolls down the board with mechanical energy. The ball hits the button on the car track, and this releases an elastic which uses elastic energy to push the car into mechanical energy. Mechanical energy is continued to be used until it reaches step E, which uses mechanical and gravitational energy interchangeably.
