Surface comparison
Mean distance at the selected ramp height. Aim for at least three trials per surface.
PHYSICAL KIT / MEASURED EVIDENCE
Your trials.
Your conclusions.
Record measured stopping distances at different ramp heights and surfaces. Keep the same car, ramp, release method and measuring reference point.
Our submitted trial record
Fixed height: 25 cm · Prediction: 90 cm · Front-wheel measurement · Three trials per surface. Every run reached the road end. Recorded means: smooth 100 cm, felt 97.67 cm, sandpaper 90 cm.
