Gravity & Orbits

Gravity is the invisible sculptor of the universe. In this course you will fling planets around a star in a gravity sandbox, launch a rocket and feel the fight between thrust and weight, prove Kepler’s laws with your own eyes, and find out what you would weigh on Jupiter.

You will learn: doneNewtonian gravity intuition doneOrbit = falling sideways doneThrust, fuel and rocket staging doneKepler’s three laws doneMass vs weight

Lessons

1 gesture Orbital Sandbox Drag and release to launch planets around a star — find the perfect speed for a stable orbit before they crash or escape. Simulation 18 min done 2 rocket_launch Rocket Launch Set your thrust and fuel, hit IGNITE, and fight gravity all the way to the edge of space at 100 km. Simulation 16 min done 3 animation Kepler’s Laws Stretch an orbit’s eccentricity and watch the planet sweep equal areas in equal times — Kepler’s laws live on your screen. Simulation 15 min done 4 fitness_center Weight on Other Worlds Pick a world, drop a ball from 10 metres, and see what your weight would be on the Moon, Mars, Jupiter — even the Sun.
