Question
1. Name the two categories that all energy in the universe can be categorized into and describe them Category A Category B Energy, in both forms above, is defined as the capacity to do work 2. What is work? 3. Describe one example from your daily life of each of the energy categories tem question #1. Be dnaled anl SPECIFIC Category A esample- Category B esample The first law of Thermodynamics states that energy cannot be created nor destroyed. Therefore the total amount of energy within a system will always remain the same. This energy is merely transferrod between calegories 4. Describe two examples of energy transfers, one in the direction of Catepory A o Category B and the other in the opposite direction. Energy Transfer Category A a Category B- Energy Transfer Category B a Category AExplanation / Answer
1. Kinetic energy and potential energy.
2. Work is the transfer of energy from the surrondings of the system to the system or vice versa by forces external to it.
3. Example of potential energy, a car at rest that contains petrol/diesel, a fuel to give it the potential to perform work possess potential energy.
When this fuel is burned potential to kinetic cycle is started and the car exhibits kinetic energy when the work is being done.
4. Category A to B - above example
Categories B to A- a wind up toy, you first do the work which is stored as the potential energy
