In Newton's Law, players drop black holes and disturb the path of a traveling planetoid, with the goal of pulling it into a stable orbit. Moving the black hole (or 'teleporting') allows you to fine tune the orbit from a wide ellipse to a perfectly circular orbit. Simple but addictive, Newton's Law is four games in one, letting everyone play with gravity!
Newton's Aquarium is an interactive physics package that helps students visualize and understand Newton's Law of Universal Gravitation. While creating and exploring their own solar systems, students encounter the core concepts in classical physics.
