Physics Formulas Sheet

A handy revision sheet of key physics formulas — motion, forces, energy, electricity, and more.

Motion (Kinematics)

Velocity	v = u + at	u = initial, a = acceleration, t = time
Displacement	s = ut + ½at²
Velocity²	v² = u² + 2as
Average velocity	v̄ = (u + v) / 2

Forces & Momentum

Newton's 2nd law	F = ma
Weight	W = mg
Momentum	p = mv
Impulse	F·t = Δp
Friction	f = μN	μ = coefficient of friction

Work, Energy & Power

Work done	W = F·s·cosθ
Kinetic energy	KE = ½mv²
Potential energy	PE = mgh
Power	P = W / t = F·v

Electricity

Ohm's law	V = IR
Electrical power	P = VI = I²R
Charge	Q = It
Energy	E = Pt
Resistors in series	R = R₁ + R₂ + …
Resistors in parallel	1/R = 1/R₁ + 1/R₂ + …

Waves & Gravitation

Wave speed	v = fλ
Frequency & period	T = 1 / f
Gravitational force	F = GMm / r²
Centripetal force	F = mv² / r

Heat

Heat gained/lost	Q = mcΔT	c = specific heat capacity
Latent heat	Q = mL
Ideal gas law	PV = nRT

🔬How to use this formula sheet

This physics formula sheet gathers the equations you use most in school and early college physics, grouped by topic so they're quick to find during revision. Each formula lists what its symbols mean where it helps. Keep it open while you practise problems, or print the page for a wall reference.

💡Revision tips

Don't just memorise — practise rearranging each formula to solve for any variable.
Always check your units; a formula only works when quantities are in consistent units.
Learn what each symbol represents, not just the letters, so you can spot which formula a question needs.

💡 Frequently Asked Questions

Which syllabus is this for?+

These are the core formulas common to most school boards (CBSE, ICSE, state boards) and introductory college physics. Always cross-check against your specific syllabus.
