Formula Sheet — Motion in a Straight Line

Important formulas and equations from Motion in a Straight Line for NEST Physics.

Formulas — Motion in a Straight Line

Position, Displacement & Distance

Displacement = Δx = x₂ - x₁
Distance = Total path length

Velocity & Speed

Average velocity = v̄ = Δx/Δt = (x₂-x₁)/(t₂-t₁)
Instantaneous velocity = v = dx/dt = lim(Δt→0) Δx/Δt
Average speed = Total distance/Total time
v_av = (v₁t₁ + v₂t₂ + v₃t₃...)/(t₁ + t₂ + t₃...)

Acceleration

Average acceleration = ā = Δv/Δt = (v₂-v₁)/(t₂-t₁)
Instantaneous acceleration = a = dv/dt = d²x/dt²

Kinematic Equations

v = u + at
s = ut + ½at²
v² = u² + 2as
s = (u + v)t/2
S_n = u + (a/2)(2n-1)
