The 2025 Reference Tables hold the constants, equations, spectrum and circuit rules you are expected to find and apply, not memorize. They have been used since the June 2026 exam, and every student gets a clean copy, so practice with them from the start.
Physical constants, prefixes for powers of 10 and the vector relationships.
Equations for motion and forces, and for energy: kinetic, potential, work, power, thermal energy and efficiency.
Equations for waves and electromagnetic radiation, including refraction and the mirror and lens equation, and a chart of the electromagnetic spectrum.
Practice the way you will use them
Keep a copy beside you for every practice set, and find each equation rather than recalling it.
Match each symbol to its meaning and unit before you substitute.
Use them as evidence: say which relationship supports your claim.

A 0.50 kg ball is dropped from rest from a balcony. A motion sensor records its speed at three heights (table). Taking g = 9.8 m/s2 and the ground as the zero of potential energy, which conclusion do the data best support?
Question 2
Each photon given off by a small LED carries 1.9 eV of energy. Use the reference tables. In which part of the electromagnetic spectrum is this light?
