Force and Momentum
Trolley, light gates & friction-compensated ramp
Verify Newtons Second Law by transferring masses between a dynamics trolley and a hanger. Light gates record t₁, t₂ and T; plot m·T against Δv to find the system mass.
"Every body continues in its state of rest, or of uniform motion in a straight line, unless it is compelled to change that state by forces impressed upon it."
Collision Analysis Lab
Video-based momentum investigation
Upload a video of a collision, calibrate a real-world scale, mark each ball frame-by-frame, draw velocity vectors and measure angles to investigate conservation of momentum.
