Mechanics Formulas Flashcards
v = Δd/Δt
velocity = change in distance / change in time
a = Δv/Δt
acceleration = change in velocity / change in time
vf = vi + at
final velocity = initial velocity + acceleration x time
d = vit + 1/2 at^2
distance = initial velocity x time + half acceleration x time squared
d = (vi + vf) / 2 x t
distance = (initial velocity + final velocity) / 2 x time
vf^2 = vi^2 + 2ad
final velocity squared = initial velocity squared + 2 x acceleration x distance
ac = v^2 / r
centripetal acceleration = velocity square / radius
F = ma
Force = mass x acceleration
τ = Fd
torque = force x distance
F = -kx
Force = - spring constant x string stretch or compression
Fc = (mv^2) / r
centripetal force = (mass x velocity squared) / radius
p = mv
momentum = mass x velocity
Δp = FΔt
impulse = Force x change in time
