ENERGY and Energy Transformations

Identify the Energy Transformations Involved in the Human Body THE HUMAN BODY IS In-Between: AN ENERGY • Electrical Signals (Electrical) Output: • Chemicals TRANSFORMATION • Motion (Kinetic) (Chemical) • Waste (Chemical) MACHINE • Sound (Sound) Input: • Food (Chemical) • Light (Radiant) • Sound (Sound) • Heat (Thermal)

What is energy? Energy – the capacity to do work or to accomplish a task Energy Transformation - the change of energy from one form to another

Types of Energy Define the different types of energy • Use Pg 128 -129 to read about and produce a definition • Include chemical potential energy, sound energy, radiant energy, nuclear energy, electrical energy, thermal energy, gravitational potential energy, kinetic energy and elastic potential energy • Complete Page 129 Q # 1, 2

Examples of Energy Transformation Machines! • Car – From: fuel (chemical) – To: motion (kinetic), heat (thermal), noise (sound) • Generator – From: fuel (chemical) or falling water (gravitational potential/kinetic) – To: electricity (electrical) • Can you think of one?

Energy Transformation Equations → • Use an arrow ( )to indicate an energy transformation has taken place • Example: A Car’s heater Takes in Gas → Moves engine Chemical → Kinetic → Produces Heat → Thermal
