Physics Simulators
Formulas are easier to remember when you've watched them move. Every simulator on this page is free, works on your phone, and comes with the underlying equations spelled out.
Projectile Motion
Change the angle, the speed, or the gravity and watch the trajectory update in real time.
Coulomb's Law
Drag charges around the field. Watch the force vectors and field arrows update.
Ray Optics
Move the object, swap between convex and concave, change the focal length. See the image form via three principal rays.
Wedge & Friction
Adjust the incline angle, mass, and friction. See the full free-body diagram and watch the block slide.
Pulley (Atwood)
Two masses, one rope, one ideal pulley. Change the masses and see the tension and acceleration update.
More simulators coming soon — SHM, wave interference, Bohr's atom, LC circuits, and more.
