Study Notes
Waves
- The highest point of a wave is known as the crest.
- The distance from the wave's crest to its resting position is known as amplitude.
- The length of a wave between the same points of two waves is called wavelength.
Signals
- Analog signals are made of waves with a continuous pattern.
- Digital signals contain binary code of zeros and ones.
Sound
- Sound waves can travel through solids, liquids, and gases.
- The sound's pitch is determined by the frequency of the wave.
Instruments
- The string family of instruments manipulates sound waves to make music.
Electricity
- Static electricity stays in the place it was created and doesn't move from one place to another.
- Current electricity is the form of electricity when an electrical charge is given a path to move through.
- Conductors are things that allow easy travel of electricity.
- Electromagnetic induction is the process of generating electricity by making electrons move around each other.
Energy
- Kinetic energy is the type of energy due to motion.
- Potential energy is the type of energy stored, or due to position.
- The term used for the process of changing energy from one form to another is energy conversion.
- According to the Law of Conservation of Energy, the total amount of energy in the Universe remains constant.
- The Law of Conservation of Energy states that the total energy of a system remains constant.
Energy Conversion
- Chemical energy is converted to kinetic energy in a scenario such as a car engine.
- Chemical energy is converted to mechanical energy in a car engine.
- When you turn on a light in your bedroom, electrical energy is converted to light and heat energy.
- When you use a microwave, electrical energy is converted to heat energy.
- When a person moves, chemical energy is converted to kinetic energy.
- Mobile phones work by using electrical energy.
- A gasoline engine burns gasoline and generates mechanical energy for a car to move.
