Length, Angle & Time

Arrange calibrated rulers, a protractor, and timer around a simple motion setup.

Learning objectives

Use the prepared scene to investigate the following physical ideas:

Length measurement
Angle measurement
Elapsed time

Available controls

The workspace lets you pause and play the scene, select its objects, edit the starting properties described below, reset the scene, and inspect configured live graph measurements.

Rotate and align the ruler with the ramp.
Use the protractor to compare the ramp angle.
Press Play and use the stable simulation timer.

Expected observations

Readable scales allow direct position and angle estimates.
Measurements do not affect the mechanics unless made physical.

Model limitations

On-screen readings depend on zoom, display resolution, authored scale, and manual alignment. The tools are educational aids rather than calibrated instruments.

Simulation output is educational and approximate. Verify important results with independent calculations or physical measurements.
