EXPLORE THE LAB

Choose a workspace

38 prepared investigations. The same objects and interaction rules connect every experiment.

Setups and captured readings recover on this device. Kept trajectories last for this session.

EXPERIMENT SETTINGS

Controls

Controls labelled live preserve motion. Other setup changes start a fresh run; kept runs and captured readings remain available.

Changing sliding friction μk scales static friction μs too; μk = 0 gives a smooth surface. Edit μs separately for a specific static limit.

GPE reference height / mChanges the reference, preserving motion. Show force arrows Lock experiment setup

Forces on each object

All solid arrows use the same scale. The dashed arrow resolves the pull along the guide; it is a component, not an extra force. Hard collisions are impulses, not continuous force arrows.

About this model

Numerical error is shown separately. Internal/deformation energy includes idealised impact loss. Electrical input uses a teaching energy port, not a full motor circuit.
