Kinematics Lab
Rolling Ramps
Predict, run, and compare motion on inclined planes — single trials, head-to-head races, and free-body / energy overlays.
Velocity vs. Time
Race Results
Pick a Race Lab preset, then use Run Race from the top or side panel.

Investigation Notes
- Increase the angle to compare acceleration against
sin(theta). - Change the object shape to see how rotational inertia affects rolling speed.
- Lower friction until the lab switches from pure rolling to slipping.
- Use Race Lab presets to reveal ties, winners, and no-motion cases.
