A complicated light switch

https://youtu.be/TiMyZbi8Hqg?feature=shared

My Plan:

Energy transformations:

• Gravitational ~ mechanical (ball falls)
• Elastic ~ mechanical (elastic and car)
• Mechanical ~ magnetic -> mech (car magnet ball)

Types of energy:

• Mechanical ~ anything moving (ex. ball on ramp)
• Gravitational ~ the ball waiting to fall
• Elastic ~ the elastic to launch the car
• Electrical ~ turning on/off the light switch
• Magnetic ~ when the two magnets repel each other

Simple machines used:

• Wedge ~ to hold mallet from light switch
• Wheel and axel ~ on the toy car
• Inclined plate ~ for the ball to roll down

 

Steps:

A:pull car back into elastic and release the car launching it forward

B: the magnet on the car repulses the other magnet with the magnetic force

C: the 2nd magnet fall and hit the ball sending it down the slope

D:the ball falls into the cup causing the cup to fall

E:the falling cup pulls down the wedge separating the switch from the mallet

F:the mallet falls and hits the switch turning on or off the light
