Physics formulas are absolutely essential: armed with them, anyone who has decided to study this science can feel entirely at home in the world of physics. Solving physics problems without a knowledge of the formulas is unthinkable. But it is practically impossible to remember every formula, and it is important, especially for a young mind, to know where to find a particular formula and when to apply it.
In specialised textbooks the physical formulas are usually distributed among the corresponding sections, in among the body text, so searching for them there can take a good deal of time, all the more so if you suddenly need one urgently!
The physics crib sheets below contain all the main formulas from the physics course, which will be useful to pupils at school and students at university.
Mechanics (kinematics, dynamics and statics)
Molecular physics. The properties of gases and liquids
Thermodynamics
Electrical and electromagnetic phenomena
Electrodynamics. Direct current
Electromagnetism
Oscillations and waves. Optics. Acoustics
Quantum physics and relativity
