Physical Science: Conservation & Energy Transfer (Transfer of Energy,…

- - - - Example: the warm air from a heater rises, cools down, then sinks back down to the floor (3)
        Convection can be enhanced with a ceiling fan (3)
- - - - Energy is always conserved (3)
      - The amount of energy in a system always stays the same (3)
      - Energy can change forms to be transferred between objects (3)
  - - - Kinetic Energy-
        the energy an object has because of its motion (3)
        
        Mechanical Kinetic Energy-
        moving objects (3)
        
        Thermal Energy-
        vibrating molecules that affect temperature (3)
        
        Electromagnetic Energy-
        light waves (both visible and invisible) (3)
        
        Sound Energy-
        molecules bumping into each other to transmit sound (3)
        
        Electric Energy-
        the flow of electrons (3)
      - Potential Energy
        
        Gravitational Potential Energy/Mechanical Potential Energy-
        stored in the height of an object (3)
        
        Elastic Energy-
        stored in the compression of stretching of elastic materials (3)
        
        Nuclear Energy-
        stored in the nucleus of radioactive atoms (3)
        
        Nuclear Fission-
        atoms are split and that energy is released (3)
        
        Chemical Energy-
        energy stored in chemical bonds (3)
        
        when the bond is broken, the chemical energy can be released (3)
        
        food, oil, gas, firewood and coal are all sources of chemical energy (3)
- - - - The energy is absorbed by plants and the plants use this energy to grow and thrive (3)
        
        The plants are consumed by humans and other animals which becomes stored energy in the body (3)
        
        When we move and exercise, we release stored energy- this is called mechanical energy (3)
