Energy forms and changes simulation answer key

Energy Transfers Simulation 1. Open the pHet simulation: Energy Forms and Changes and the Systems tab. Be sure to click the box with energy symbols so you can see the energy types 2. Arrange the simulation to create each of the different configurations pictured below. Then, run the simulation for at least 30 seconds. 3. Describe what occurred and then name the transformations that you saw Configuration Description of what occurred Transformation Tap on high water wheel, beating beaker of water . Mechanical lectrical • Electrical Sun without clouds, solar panel, incandescent light * Kettle, water wheel, fan Bike, water wheel, incandescent light Bike, water wheel, fluorescent light Questions: 1. Which is more efficient, the incandescent or fluorescent bulb? Explain your choice 2. Why did you have to feed the biker?

configuration energy converted into energy. electrical energy turns into heat enersy due to which E. E – electrical energy and then electrical energy to heat Description is The potential energy of water turms the wheel of dynamo and electrical energy is produced. Now this the tomperature of water increases. [1] In this Configuration Mechanical energy [2] SOLAR ENERGY -> ELECTRICAL ENERGY [EE] TEE] LIGHT ENERGY The energy of all the photon Coming from Sun emit the electron from Solar panel. This constitute electric Current which when flow to incandescent lamp it glow B) MECHANICAL ENERGY → ELECTRICAL ENERGY [6E] – KINETIC ENERGY. The steam coming out from kettle turns the wheel of turbine, which produce electrical energy. This energy is used by fan to increase kinetic energy of wind. L] MECHANICAL ENERGY –> ELECTRICAL ENERGY [EE] E E LIGHT ENERGY The mechani work done by biker On bike or cycle Convert Is use to turn turbine wheel. This cause electricity production, which when pass to bulb it flow. MECHANICAL ENERGY –> ELECTRICAL ENERGY (EE) E. E LIGHT ENERGY. – The work done by biker turns the water wheel of turbine or dynamo, which produce electrical energy. When this energy passes to flourescent bulb it glow. 01. Lof Fluorescent bulb is more efficient then incandescent bulb because of its more efficiency. These bulb use Light emitting diode whose resistance is almost neglisible O Biker need to feed because he is doing work on doing work he lost his energy. To do work continuou sly, he deed nonstop supply of energy for this he need food.
