Physics
Motion, forces, energy and circuits.
- Speed, distance and timespeed = distance ÷ time — keep the units consistent.
- Calculating accelerationacceleration = change in velocity ÷ time.
- Newton's second law (F = ma)Resultant force = mass × acceleration.
- Newton's third law pairsEvery force has an equal and opposite force on the other object.
- Mass vs weightMass is matter (kg); weight is gravity's force on it (N).
- Kinetic and gravitational potential energyKE = ½mv²; GPE = mgh.
- Conservation of energyEnergy is transferred, never created or destroyed.
- Ohm's law (V = IR)Voltage = current × resistance.
