Physics Topic
Newton's Laws of Motion
Understand why objects move, accelerate, and interact. Newton's three laws explain everything from a sliding book to a launching rocket using force, mass, and acceleration.

Newton's Laws Poster
A single cohesive visual covering all three laws with annotated force diagrams, inertia, F = ma, and action-reaction pairs with real-world examples.
View Poster →Forces and Free-Body Diagram Tool
Explore Newton's second law with interactive free-body diagrams on surfaces, inclines, and connected systems. Adjust forces and watch acceleration update in real time.
Open Tool →Momentum and Impulse Lab
Apply variable forces over time and see real-time force-time curves. Calculate impulse as area under the curve, compare to momentum change, and explore crumple zone physics.
Open Lab →The Three Laws
- 1st Law: An object at rest stays at rest unless acted on by a net force.
- 2nd Law: F = ma. Net force equals mass times acceleration.
- 3rd Law: Every action force has an equal and opposite reaction force on a different object.
