1. Show your choice of system in the energy flow diagram, unless it is specified for you. **Always include the earth in your system. 2. Decide if your system is frictionless or not, and state this. 3. Sketch an energy bar graph for the initial situation. 4. Complete the analysis by showing energy transfers and the final energy bar graph. 1.
Generate: Make electricity by turning a magnet inside coils of wire. Heat energy: Heat energy is the energy produced by the motion of particles within an object. Kinetic energy: The kind of energy in moving things. Law of conservation of energy: The idea that energy can never be created or destroyed, only changed from one form into another.
An energy flow diagram is a visual way to show the uses of energy in a system. A simple diagram for the energy flow in a mobile phone is shown below. This shows how energy is converted from one form into another.
Energy Ws #1: Reaction Rates 1. Chemical reactions occur when reactants collide. For what reasons may a collision fail to produce a chemical reaction? 2. If every collision between reactants lead to a reaction, what determines the rate at which the reaction occurs? 3. What is the activation energy of a reaction, and how is this energy related ...
