PHYSICS FORMULAES:
Speed: v = s / t
Average speed = total distance / total time
Acceleration: a = Δv / Δt
Force: F = ma
Weight: W = mg
Density: ρ = m / V
Pressure: p = F / A
Moment = force × distance
Work done: W = Fd
Kinetic energy: KE = ½mv²
Gravitational potential energy: GPE = mgh
Wave speed: v = fλ
Frequency: f = 1 / T
