2. Buoyancy experiment—relationship between mass and submerged depth, derivation of upthrust equation, cylindrical beaker assumptions, systematic error correction
3. Refractive index of salt solutions—density determination method, refractive index vs salt mass graph, sinθ₁ vs sinθ₂ plotting for gradient (n), uncertainty in angle measurements and refractive index
4. Electric motor efficiency—gravitational potential energy vs energy supplied, graph plotting, efficiency formula use, decreasing efficiency at higher mass, experimental consistency
5. Bungee rope stress test—breaking stress calculation from mass and diameter, comparison to manufacturer value, safety justification for small-diameter sample use in lab tests
