Free Fall Kinematics Lab: Measure g, Graph d vs t², Air Resistance + Answer Key
Make kinematics hands-on, visual, and AP Physics–ready with this Motion & Kinematics: Free Fall Lab. Students measure real free-fall times from multiple heights, calculate experimental g, and then do what strong physics students must learn: use graphs to linearize a non-linear relationship by plotting d vs. t² and extracting g from the slope.This lab also includes an engaging “why the model breaks” extension with air resistance and terminal velocity using coffee filters—plus built-in error analy

Standing Waves Lab on a String (Harmonics) v=fλ v=√(T/μ) Graphing + Key
This is the standing waves + harmonics lab that finally makes wave equations feel real. Students create clear standing wave patterns, identify nodes and antinodes, calculate wavelength for each harmonic (λ = 2L/n), verify that harmonic frequencies are integer multiples of the fundamental (fₙ = n·f₁), and show that wave speed stays constant across harmonics (v = fλ).Then the lab goes one step deeper (and more AP Physics-ready): students vary tension, calculate v = √(T/μ), graph v vs √T, and use t
