Gravity Well

The Gravity Well is a highly engaging physical model that helps middle school students visualize gravity, orbits, and interactions between mass and motion. By rolling balls across a stretched fabric surface, students can see how objects curve paths, spiral inward, or maintain orbit-like motion—making abstract space science concepts concrete and observable.

This model is especially effective for introducing gravitational interactions without heavy math. Students can experiment with mass, speed, and starting position to observe patterns in motion and make predictions about outcomes. These explorations naturally lead to discussions about why planets orbit stars, why satellites stay in motion, and how gravity influences large-scale systems in space.
