Steps of the machine
- Medium ball #1 is placed at the top of the inclined plane
- Medium ball #1 rolls down the inclined plane
- Medium ball #1 crashes into the piece of cardboard in between medium ball #1 and #2
- Medium ball #2 starts rolling down the inclined plane
- Medium ball #2 falls into the bucket
- The bucket get dropped down by the pulley
- The bucket knocks over domino #1
- Domino #1 starts a chain reaction with the other dominoes, causing them to fall over one at a time
- The last domino pushes the toy car
- The toy car rides down the inclined plane
- The toy car pushes the fidget spinner (wheel and axle)
- The fidget spinner releases small ball #1
- Small ball #1 falls into the tube with the jump wire connectors
- The jump wire connectors receive energy from the batteries in the circuit
- The jump wires connectors send an electric charge through the jump wires
- The electric charge turns the light on
Simple Machines used:
- Inclined plane
- Wheel and Axle
- Pulley
Energy Transfers:
- When Medium Ball #1 is at the top of the inclined plane, it has gravitational potential energy.
- When Medium Ball #1 starts rolling, the gravitational potential energy is transformed into mechanical energy, causing the ball to move.
- When Medium Ball #1 crashes into Medium Ball #2, Medium Ball #1 transfers the mechanical energy to Medium Ball #2, and Medium Ball #2 starts rolling.
- Medium Ball #2 falls into the pulley because of gravitational energy.
- When the pulley starts moving, the gravitational energy is transformed into mechanical energy.
- The mechanical energy is transferred to the first domino when the pulley touches it.
- The dominoes tip over one by one due to mechanical energy.
- The last domino transfers the mechanical energy to the toy car.
- When the toy car rests at the top of the inclined plane, it has gravitational energy.
- When the toy car starts moving, the gravitational energy is transformed into mechanical energy.
- When the toy car crashes into the fidget spinner, the toy car transfers its mechanical energy to the fidget spinner.
- The fidget spinner moves because of mechanical energy.
- The fidget spinner releases Small Ball #1, which, when it is at rest, has gravitational energy.
- The ball falls, transforming the gravitational energy into mechanical energy.
- When the ball rolls down the inclined plane, it continues to use mechanical energy.
- During the time when the ball is not touching the jump wire connectors, the batteries have chemical energy.
- When Small Ball #1 touches the jump wire connectors, the chemical energy in the batteries is transformed into electrical energy.
- The electrical energy flows through the wires in the circuit.
- When the electrical energy reaches the light, the light turns the electrical energy into light energy, making it light up.
