Mechanics formula sheet

58 rows · 6 sections · PhysRef · sample of the first 6 rows

Mechanics formula sheet. Every mechanics equation in PhysRef on one sheet — 58 formulas across 6 topics, each with its equation set in real maths, a symbol key and the SI unit of every symbol.
Quantity	Equation	Symbols	SI units
Kinematics
Velocity	$v = \frac{\Delta x}{\Delta t}$	v = velocity · Δx = displacement · Δt = time interval	v: m/s · Δx: m · Δt: s
Acceleration	$a = \frac{\Delta v}{\Delta t}$	a = acceleration · Δv = change in velocity · Δt = time interval	a: m/s² · Δv: m/s · Δt: s
Kinematic Equation 1	$v = v_0 + at$	v = final velocity · v₀ = initial velocity · a = acceleration · t = time	v: m/s · v₀: m/s · a: m/s² · t: s
Kinematic Equation 2	$x = x_0 + v_0 t + \frac{1}{2}at^2$	x = final position · x₀ = initial position · v₀ = initial velocity · a = acceleration · t = time	x: m · x₀: m · v₀: m/s · a: m/s² · t: s
Kinematic Equation 3	$v^2 = v_0^2 + 2a(x - x_0)$	v = final velocity · v₀ = initial velocity · a = acceleration · x = final position · x₀ = initial position	v: m/s · v₀: m/s · a: m/s² · x: m · x₀: m
Kinematic Equation 4	$x = x_0 + \frac{1}{2}(v_0 + v)t$	x = final position · x₀ = initial position · v₀ = initial velocity · v = final velocity · t = time	x: m · x₀: m · v₀: m/s · v: m/s · t: s

Built from the 58 mechanics entries in the PhysRef reference, grouped by the topics that category page uses. Every equation here is free to read on its own page at /formulas.

Every row on this sheet is also free on its own page — browse the Mechanics formulas. Premium pays for the sheet, not the physics.
