Free physics certificationPhysics Certification
Solve each problem in steps on a board that checks them: choose the axes, draw the forces, write the equations with units, then solve. Each of the three sections, Mechanics, Electricity and Magnetism, and Optics, Waves and Modern Physics, earns its own verifiable certificate.
Inside the Physics course
Each section below issues its own certificate when completed. Browse the full course to see every lesson and problem.
01
MechanicsForces, motion and energy from zero: vectors and Newton's laws, friction and inclines, kinematics and projectiles, work and energy, springs, momentum and collisions, circular motion, simple harmonic motion and gravitation.
02
Electricity and MagnetismCharges and fields from zero: Coulomb's law, the electric field and potential, conductors and capacitors, electric circuits and Kirchhoff's laws, magnetic fields and forces, and induction.
03
Optics, Waves and Modern PhysicsLight and matter from zero: reflection, refraction and lenses, waves and interference, light as a wave through slits and gratings, photons and the photoelectric effect, the Bohr atom, and the nucleus: radioactive decay, half-life and binding energy.
How it works
Three steps from your first vector to a certificate you can show off.
- 01
Pick a course
Choose a physics course and start with the first lesson, no card and no signup wall.
- 02
Solve through the section
Each section is a series of lessons and problems you solve in steps: axes, forces, equations with units, then the answer, each step checked.
- 03
Earn and share your certificate
Finish the section to unlock a verifiable certificate with a unique ID. Add it to LinkedIn, a school application or your CV in one click.
What you will prove
Each Physics certificate certifies that you solved the problems yourself, step by step, not that you watched a lecture.

How do I get a physics certificate on Coddy?
Pick a physics course and complete a section: finish every lesson and problem in it. The certificate is generated the moment the last lesson is done and added to your account.
Is a physics certificate from Coddy accredited?
No. Coddy is not a school and does not award academic credit. The certificate records that you solved every problem in a section yourself, on a board that checks each step, which a tutor, a teacher or a portfolio can use.
Are Coddy's physics certificates free?
Yes. Every certificate is free to earn, view, download and share, with no subscription needed.
How does someone verify a physics certificate?
Every certificate has a unique ID and a public URL. Anyone can paste the ID into the verifier on this page or open the URL to see that it is genuine and which section it was issued for.
Can I put a physics certificate on LinkedIn?
Yes. The certificate page has a one-click Add to LinkedIn button, a downloadable PDF and a public link.
How many physics certificates can I earn?
One per section of every physics course. The physics course has three: Mechanics, Electricity and Magnetism, and Optics, Waves and Modern Physics.
