Gear Ratio Explorer Interactive
Investigate how meshing gears transmit motion. Students compare tooth counts, rotation direction, gear ratios and speed or torque trade-offs in illustrative gear trains. The full interactive is available to licensed Education Universe users.
Years 8–10ExplorerGears
Learning outcomes
- Calculate a simple gear ratio from tooth counts
- Explain rotational direction of meshing gears
- Predict speed and torque changes
Teaching guidance
Ask students to predict the direction and approximate output rotations before running the gear train.
