PHY 205 Lecture Notes - Lecture 41: Drawing Pin, Heat Sink, Lightning
Document Summary
For every action there is an equal and opposite reaction. States that energy cannot be created or destroyed but only changed from one form into another or transferred from one object to another. Ex) playing pool, someone running into another person and making them fall down, moving car hits a parked car. Mechanical energy is the energy of motion that does the work. Heat energy is energy that is pushed into motion by using heat. Electrical energy is when electricity creates motion, light or heat. Gravitational energy is motion that is caused by gravity. The way heat is transferred from one area to another when there is a "bulk movement of matter. " It is the movement of huge amounts of material, taking the heat from one area and placing it in another. Ex) boiling water because the heat passes from the burner into the pot, heating the water at the bottom.
