## Class 10 Physics All Formulas

Physics formulas Class 10 PDF will not only help class 10 students to prepare for their class 10 board exams but also in their later stages when they set out to prepare for competitive medical and engineering entrance exams like NEET and JEE. These formulas are the most used and commonly occurring in Physics.

Some of the Students fear physics due to its complex numerical problems. But if students become familiar with the physics formulas, the subject can be a lot more interesting. Remembering all the physics formulas can get hard. Keeping this in mind, we have created a comprehensive list of all class 10 physics formulas.

### Class 10 Physics All Formulas

• Mirror formula, 1/v + 1/u = 1/f
• Magnification, M = v/u = h2/h1
• Lens formula 1/v – 1/u = 1/f
• Law of refraction, n = Sin i/sin r
• Refractive index, n2 = v1/v2 or n1 = v1/v2
• Absolute Refractive Index

Electricity

• Electric Current, I = q/t
• Potential difference, v = W/Q
• Ohm’s law, V = IR
• Resistivity, ρ = RA/L
• Conductivity = L/RA
• Resistors in series Formula
• Resistors in parallel Formula
• Electric power, P = W/t = VI = I2R
• Electric energy
•  Joule’s law, H = I2RT
