  1. Second Semester
    1. Voltage
      1. Electric potential energy per unit charge, measured in joules per Coulomb (volts).
        1. It is the difference in charge between two points
          1. Equation: Electric Current = Voltage divided by Resistance
          2. Polarization
            1. The process of transforming unpolarized light into polarized light.
              1. Polarization is usually used in sunglasses and is beneficial for blocking out the glare of shiny things.
                1. Polaroid filters are made of a special material that is capable of blocking one of the two planes of vibration of an electromagnetic wave.
                2. Simple Harmonic Motion
                  1. Mass on a spring when it is subject to the linear elastic restoring force given by Hooke's Law.
                    1. Equation: (Hooke’s Law) Force = -Spring Constant x Displacement of the Spring
                    2. Drivien Harmonic Motion
                      1. It is when the amplitude of the oscillation is forced to increase.
                        1. Forced applied to this must be at the right frequency, the natural frequency.
                        2. Damped Harmonic Motion
                          1. It is when the amplitude of the oscillation decreases due to an outside force
                            1. It decays exponentially
                              1. An example of this could be found in the springs of your bed when weight is put on it.
                              2. Sound
                                1. A mechanical wave that is created by a vibrating object.
                                  1. Sound waves travel in longitudinal waves that are parallel to the direction of energy transport.
                                    1. They need a medium to travel through.
                                    2. Capacitors
                                      1. An electrical device for storing charge.
                                        1. It is made from two or more plates of conducting material separated by a layer or layers of insulators.
                                          1. A capacitor can store energy to be given to a circuit when needed.
                                            1. Equation: Capacitance = Charge divided by potential difference.
                                            2. Wave Behaviors
                                              1. Reflection is when a wave hits a boundary and bounces back.
                                                1. Refraction is when a wave passes into another medium causing a change in speed and direction of the wave.
                                                  1. Diffraction is when a wave hits an obstacle or a whole and spreads around the edge.
                                                    1. Interference is when two or more waves try to pass through the same place at the same time.
                                                    2. Diverging Lens

                                                        1. They are thin across their middle and thick at their upper and lower edges.
                                                          1. This type of lens is used for people who cannot see clearly when they are far away from something.

                                                                    1. Second Law: The direction of the force vector is the same as the direction of the acceleration vector. Equation: Force= Mass x Acceleration.
                                                                      1. Third Law: For every action there is an equal and opposite reaction. Example: If you push in one direction off of a wall while sitting in a rolling chair, the chair will then move in the opposite direction.
                                                                      2. Scientific Method
