MATTER AND ENERGY
  1. Transformations
    1. Interactions
      1. Physical agents
        1. WORK

          Annotations:

          • Work is done when a force acts on an object and causes its displacement. The force must act totally or partially in the direction of the movement.
          1. Force
            1. Displacement
              1. ENERGY
                1. Systems

                  Annotations:

                  • Depending on if there is an exchange of matter and/or energy with the sorroundings, a system can be:
                  1. Isolated

                    Annotations:

                    • Neither mater nor energy can be transferred to or from another system
                    1. Closed

                      Annotations:

                      • Only the energy can be transferred but not matter.
                      1. Open

                        Annotations:

                        • Matter and energy can be transferred to or from another system
                    2. Matter

                      Annotations:

                      • - Change in position - Increase or decrease in temperature - Deformation or change in shape - Change in volume
                      1. Energy

                        Annotations:

                        • Is the capacity of matter to transfer heat or to do work. As the matter transfer heat or does work, its energy decreases.
                        1. Forms of Energy

                          Annotations:

                          • - Mechanical Energy - Chemical Energy - Thermal Energy - Internal Energy - Electromagnetic Energy - Nuclear Energy - Electrical Energy
                          1. Energy Conservation

                            Annotations:

                            • Energy can be transformed from one form into another, or transferred from one body to another, but cannot be created or destroyed. So the total quantity of energy remains constant
                            1. Principle of Conservation of Mechanical Energy
                              1. Kinetic Energy
                                1. Potential Energy
                              2. Energy Degradation

                                Annotations:

                                • All forms of energy can be completely transformed into heat, but heat cannot be completely transformed into other forms of energy
                                1. Heat
                            2. Usable Source of Energy
                              1. Non-renewable

                                Annotations:

                                • From resources found in nature in limited quantities. - Fosil fuels - Nuclear Energy
                                1. Renewable

                                  Annotations:

                                  • Comes from inexhaustible natural resources. - Hydroelectric -Geothermal -Solar -Wind -Tidal
                                2. Saving Energy

                                  Annotations:

                                  • - Say no to crazy consumerism. - Turn off ligths and electrical appliances. - Buy low power consumption appliances. - Use energy saving bulbs. - Use natural light .... etc.
                                  1. Momentum Conservation Principle

                                    Annotations:

                                    • For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision. That is, the momentum lost by object 1 is equal to the momentum gained by object 2. M1.V1=-M2.V2
