Chapter 1: Motion, forces, and energy. Formula. What it means. Unit (can vary) v=d÷t. v = velocity. s = speed. t = time. Velocity. m/s (can vary) D=sxt. D = distance s = speed. Distance-Speed Time. Average speed = total. distance ÷ total time. a=v÷t. a = (v-u) ÷ t. v = u + at. g=W÷m. *2023: Free Fall = 9.8 m/s^2.
Wave speed (ms-1) = frequency (Hz) × wavelength (m) c = fλ. Frequency (Hz) = 1 Period (s) F = 1. T. Refractive index = sine of the angle of incidence, i sine of the angle of refraction, r. n = sini sinr. Refractive index = speed of light in vacuum speed of light in material. n = cv cm.

λ = Wavelength. D = Distance to screen. d = Slit spacing. n = Any integer (order of minimum/maximum). Refraction when a wave crosses a boundary between 2 media (Snell’s law). Fringe spacing in double slit diffraction. Maxima/minima on screen in double slit diffraction. c = Velocity. f = Frequency. λ = Wavelength. I = Intensity. A = Amplitude.
Boyle’s Law for changes in gas pressure at constant temperature : pressure1 (Pa) × volume1 (m3) = pressure2 (Pa)× volume2 (m3) P1V1 = P2V2. Energy (J) = mass (kg) × specific heat capacity (Jkg-1°C-1) × temperature change (°C) Q = mcθ.
