Energy Sources
Energy: The ability to do work
Types of Energy: Nonrenewable, renewable, inexhaustible Nonrenewable Energy Sources: sources that cannot be replaced once used examples: coal, oil, natural gas Renewable Energy Sources: sources that can be replaced once used examples: animals, food, biomass Inexhaustible Energy Sources examples: hydroelectric, geothermal, wind, solar |
Breadboarding and Electronic Components
Breadboard: reusable platform for temporarily built electronic circuits
Diode: allows current to flow in only one direction Resistor: an electronic component that resists the flow of electrical current Switch: an electronic component that can leave a circuit open or closed Why breadboard? It takes less time and money to breadboard a circuit than to design and fabricate a printed circuit board (PCB). Designers can observe and test circuits to ensure they function as they planned. It is very quick to change components on a breadboard which make them great for the development and testing phases. |
Mechanical System EfficiencyThe winch activity below will provide students with an opportunity to experiment with efficiencies as energy is converted from electrical input to mechanical output.
