Physics

Physics is easiest to believe when you can grab it. These free interactives put the equations themselves in students' hands, from projectile flights that obey the big four kinematics equations to a fusion reactor chasing breakeven, with worksheets and NGSS or AP alignment built in.

Cannon Kinematics

Fire a cannon on four worlds, drag the variables inside the big four kinematics equations, and watch every dotted flight obey them exactly.

Fusion Forge

Fuse two atoms against the Coulomb barrier, run the Sun's crushed core, then race ITER to breakeven in a tokamak you control.
