For class pages, LMS, and blogs

Put a simulation on a class page

Paste one iframe to put a working PhysicsLearn simulation on Google Sites, Canvas, WordPress or a class page. Start with the projectile launcher. Students need no account. Teaching calculators are here too if you want the method shown as steps.

Each simulation and calculator has its own widget page with a live preview and the snippet. Host steps live under embed in Google Sites, Canvas, Schoology, Moodle, WordPress and Notion. Lesson packs group a unit. Assistants should read how to embed PhysicsLearn. See also projectile motion.

Live embed of the projectile launcher

This is the widget as it appears on a class page, caption included if you keep the snippet whole. Drag the launch arrow and fire.

Open the projectile launcher widget page

Start with these

Four simulations: a launcher you can fire, a free-body diagram you draw yourself, a ramp you can tilt, and two carts that collide. Open a widget page for its copy box. The directory below lists every tool.

Lesson packs

A unit is several widgets on one class page, not one picture standing in for physics. Packs: kinematics, forces, collisions.

Every simulation widget

4 simulation pages. Open one for the iframe. The dump of every snippet also lives on embed graphs if you already have that query.

Projectile launcherDrag the launch arrow to set angle and speed, scrub time to read vx and vy, and measure range, max height, and flight time on Earth, the Moon, or Mars.Free-body diagram builderBuild the free body diagram for five classic scenarios and get it checked force by force, with feedback that explains every fix. Free, works on phones.Inclined plane simulatorDrag the ramp angle and friction and watch gravity split into components, the stays-or-slides verdict flip, and the acceleration update live.Collision labSet two carts colliding and watch total momentum hold still while kinetic energy drops. Drag mass, velocity and elasticity; every number updates live.

Teaching calculators

12 calculators that show the method. PhysicsLearn is simulations first. These are the step tools. Each still has its own widget page.

Centripetal force calculatorCompute centripetal acceleration and force with ac = v^2/r and Fc = mv^2/r, from speed or period. Worked examples plus the real forces behind Fc.Coulomb's law calculatorCompute the electric force between two charges with Coulomb's law, F = k q1 q2 / r^2, using k = 9.0e9. Handles microcoulombs, with AP-style worked examples.Friction calculatorCompute kinetic friction, maximum static friction, or solve for mu with F = mu N. Includes the AP Physics 1 inequality, worked examples, and common traps.Kinematics calculatorEnter any three of initial velocity, final velocity, acceleration, time, and displacement. It solves the AP constant-acceleration equations for the rest.Kinetic energy calculatorFree kinetic and potential energy calculator for AP Physics 1. Computes K, delta Ug, and spring energy in joules, with worked examples and unit tips.Momentum collision calculatorFree momentum and collision calculator: p = mv, impulse, perfectly inelastic and 1D elastic final velocities, with the conservation setup for each.Net force calculatorSolve F = ma for force, mass, or acceleration, and add two force components. Covers Newton's second law and how to find the net force on a system.Normal force calculatorFind the normal force on flat ground, on an incline, or with an extra vertical force. Formulas, worked examples, and why N is not always mg.Ohm's law calculatorSolve for voltage, current, resistance, or power from any two values, plus series and parallel equivalent resistance with worked AP-style examples.Projectile motion calculatorFree projectile motion calculator for time of flight, range, and max height from launch speed, angle, and height.
