Mechanics
Motion, forces, energy, and momentum relationships.
Kinetic Energy
KE kinetic energy, m mass (kg), v velocity (m/s).
KE = ½mv² Gravitational Potential Energy
GPE potential energy, m mass (kg), g gravitational field strength (9.8 N/kg), h height (m).
GPE = mgh Power
P power (W), W work (J), t time (s).
P = W / t Topic Focus
Motion & Energy
- SUVAT equations apply only when acceleration is constant.
- Energy is conserved in closed systems: total energy before = total energy after.
- Power measures how quickly work is done or energy is transferred.
Electricity
Voltage, current, resistance, and electrical power relationships.
Resistance (Ohm's Law)
R resistance (Ω), V voltage (V), I current (A).
R = V / I Electrical Power
P power (W), V voltage (V), I current (A).
P = VI Electrical Energy
E energy (J), P power (W), t time (s).
E = Pt Topic Focus
Electrical Circuits
- Ohm's Law: V = IR. Voltage drives current; resistance opposes it.
- Power = voltage × current. Higher power devices use more energy per second.
- Energy = power × time. Calculate energy consumption using this relationship.
Waves
Wave properties, frequency, wavelength, and wave speed relationships.
Wave Speed
v wave speed (m/s), f frequency (Hz), λ wavelength (m).
v = fλ Refractive Index
n refractive index, c speed of light in vacuum, v speed in medium.
n = c / v Topic Focus
Wave Properties
- Wave speed = frequency × wavelength. All three are related.
- Frequency measures how many waves pass per second (Hz = waves/second).
- Refractive index shows how much light slows down in a medium compared to vacuum.
