- Where does wasted energy end up? As gravitational potential energy in the surroundings As kinetic energy in the surroundings As thermal energy in the surroundings As chemical energy in the surroundings
- When we transfer kinetic energy into a system that uses magnets and a coil of wire to generate electricity by moving something in the system, we call the system a generator. In a generator, magnets transfer energy from motion into changing magnetic fields, which then transfer energy to changing electric fields These electric fields cause electrons to move and transfer electrical energy along the wire Therefore, one way to think about a generator is as a device that transforms kinetic energy (motion) into electrical energy. However, when we transfer electrical energy into a system that uses magnets and a coil of wire to turn a shaft we don't call the system a generator. Instead, we call it a motor. In a motor, moving electrons from a source causes a change in the field around a coil of wire This field will push and pull the magnets This will cause the shaft to move. Imagine that a student draws this energy transfer diagram of a motor: Q1. Provide constructive feedback to this student using the following prompts: What parts would you suggest the student add?
