Gravity Interactive Simulation

Gravity pulls every object downward with a force called its weight (W = m·g). On Earth, every kilogram weighs about 9.8 newtons. In free fall an object accelerates under gravity and drops farther each second: d = ½gt². Students can change mass and gravity and compare what happens. Use it for physics inquiry with Grades 3–4, Middle School, and High School on a projector or student device.

• How weight changes on different planets (same mass, different g)
• Why a heavier object has more weight but free-falls at the same rate
• Reading W = m·g with your own mass and gravity values
• How fall distance grows with the square of time

1. 1Predict how changing mass will affect the weight, then test the prediction.
2. 2Use evidence from the live calculation and visual to explain the result.
