Motion along a path
A ball flies along its parabola, a car drives along a road, a planet goes round its orbit, each leaving a dashed trail.
For physics teachers
Physics that really moves
Show a projectile flying along its parabola, a pendulum swinging, a spring bouncing and current flowing round a circuit. Ready-made physics objects move on their own, and your own drawings can travel along any path.
A physics lab on every slide
Objects that move on their own
Pendulums swing, springs oscillate, waves travel and Fourier circles draw a shape, while you talk.
Forces, circuits, optics and 3D
Free-body diagrams, inclined planes, pulleys, circuits, lenses and mirrors, atoms, and 3D surfaces you turn by hand.
Built for the way physics is taught
The situation first
Start with a real scene, a cannon, a car, a swing, then bring in the vectors and equations one click at a time.
Real numbers
Graphs come from equations, so the motion on the slide matches the maths you write next to it.
How it works
- Pick objects from the Science menuPendulum, spring, incline, circuit, lens, wave, atom…
- Set the numbersLength, angle, mass or voltage: the object updates as you type.
- Present, or make a videoShow it live in class or send students an MP4.
Questions
Which physics topics are covered?
Mechanics (motion, forces, inclines, pulleys, pendulums, springs), waves, electricity, optics, atoms and signals.
Can the AI make a physics lesson?
Yes. Describe the lesson, for example projectile motion for 15-year-olds, and it builds animated slides you can edit.
Do I need to code the motion?
No. Objects move on their own, and you make anything travel along a path with a few clicks.
