Core physics formulas
Before substituting values, identify the physical quantities, write their units, and check that the selected law matches the situation.
Newton's second law
F = ma
Force equals mass multiplied by acceleration.
Ohm's law
I = U / R
Current depends on the voltage and resistance of the circuit section.
How this section will grow
New entries will be organized by topic: mechanics, electricity, optics, and thermodynamics. For now, the page contains only the material that is already ready to use.
