Study Notes
Mechanics
- Kinetic energy is associated with motion.
- Acceleration due to gravity is 9.81 m/s².
- An inelastic collision occurs when two objects collide and stick together.
Thermodynamics
- Adiabatic process is when a gas expands without heat entering or leaving the system.
- Specific heat capacity is the amount of energy required to raise the temperature of 1 kg of a substance by 1°C.
- Vaporization is the phase change from a liquid to a gas at constant temperature and pressure.
Optics
- Violet light has the shortest wavelength in the visible spectrum.
- Refraction is the phenomenon of light bending as it passes from one medium to another.
- Convex lens has a positive focal length.
Wave Theory
- Amplitude of a wave is related to its energy.
- The speed of a wave is calculated by multiplying the frequency by the wavelength.
- Doppler effect causes frequency to increase when the sound source moves toward an observer.
Electricity
- A resistor in an electrical circuit resists the flow of current.
- If the voltage across a circuit is doubled, the current doubles assuming resistance is constant.
- Electrical resistance is inversely proportional to the cross-sectional area of the conductor.
