11 interactive physics simulations. Play with them — that's how intuition builds.
Build FBDs for different scenarios. Drag force arrows, check your work, and learn to identify every force acting on an object.
Apply forces to a block and watch four synchronized views: the scene, a live FBD, a velocity-time graph, and real-time calculations.
Launch projectiles at different angles and speeds. See how horizontal and vertical motion are independent — the key insight for ballistics.
Adjust velocity and watch the position-time graph build in real time. See how slope = velocity.
Smash objects together — elastic, inelastic, or explosions. Watch momentum stay constant while kinetic energy doesn't. The bar charts make it click.
Roll a ball along curved tracks and watch energy transform between kinetic and potential in real time. Add friction and see where the energy goes.
A pendulum swinging with live KE and PE bars. See energy flow back and forth, perfectly conserved.
See why velocity is tangent, acceleration points inward, and what happens when you cut the string. Destroys the "centrifugal force" myth.
Visualize uniform circular motion — see how speed stays constant while velocity continuously changes direction.
Watch a mass on a spring oscillate. See how amplitude, frequency, and spring constant are related.
Explore wavelength, frequency, and amplitude. See how changing one affects the others.
