What are the Different Energy Stores? Give a Simple Definition for Each | -Kinetic: Simply things that Move has Energy here
-Thermal: Hotter = More Energy here
-Chemical: Things that release Energy via a Chemical Reaction [Food]
-Gravitational Potential: Anything in a Field [Stationary]
-Elastic: Things that are Stretching
-Electrostatic: 2 Charges that Attract or Repel
-Magnetic: 2 Magnets that Attract or Repel
-Nuclear: Energy that's from Atomic Nuclei in Nuclear Reactions |
How can Energy be Transferred? | -Mechanically: An Object that Moves due to a Force
-Electrically: Charge moving through a Potential Difference
-Heating: Energy Transferred from a Hotter to Colder Object
-Radiation: Energy Transferred via Waves |
What is the Law of Conservation of Energy | -This is Energy can be Stored, Transferred and be Dissipated - but never Created nor Destroyed. Total Energy in a Closed System = No Net Change-Closed System = Objects that don't have any Matter being Exchanged with the Surroundings |
A Ball is Rolling up a Slope, Describe the Energy Transfers | -Energy is Transferred Mechanically [Force pushing it up the Hill] from the Kinetic Energy Store to the Gravitational Potential Energy Store |
A Bat hitting a Ball, Describe the Energy Transfers | -Kinetic Energy Store, in the Bat, is Transferred Mechanically [Force] to the Thermal Energy Store of the Bat
-Also, some of the Kinetic Energy in the Bat is also Transferred Mechanically to the Kinetic Energy Store of the Ball
-Then Finally, there is Energy being Given off [Sound] |
A Car Slows Down [No Braking], Describe the Energy Transfers | -Kinetic Energy Store in the Car is Transferred Mechanically [Because of Friction-Force] to the Thermal Energy Store of the Car and the Road |
Electric Kettle boiling Water, Describe the Energy Transfers | -Energy is Transferred from the Mains, to the Kettle's Thermal Energy Store, which is then Transferred through Heating to the Thermal Energy Store of Water |
