Displacement

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

displacement bannerDisplacement, abbreviated as d or DISP, is the change in position.  Displacement is a vector quantity having magnitude and direction, some of these include acceleration, drag, force, lift, momentum, thrust, torque, velocity, and weight.

Displacement formula

(Eq. 1)  \(\large{ d =  v \; t }\)

(Eq. 2)  \(\large{ d = x_f  - x_i }\)

(Eq. 3)  \(\large{ d = v_i \; t + \frac {1}{2} \; a \; t^2  }\)

(Eq. 4)  \(\large{ d =  \frac {P \; t}{F}   }\)

Where:

\(\large{ d }\) = displacement

\(\large{ a }\) = acceleration

\(\large{ F }\) = force

\(\large{ x_f }\) = final position

\(\large{ x_i }\) = initial position

\(\large{ P }\) = power

\(\large{ t }\) = time

\(\large{ v }\) = velocity

\(\large{ v_i }\) =  initial velocity

Solve for:

\(\large{ F =  \frac {P \; t}{d} }\)

\(\large{ P =  \frac {F \; d}{t} }\)

(Eq. 1)  \(\large{ t =  d \;v }\)

(Eq. 2)  \(\large{ t =  \frac {F \; d}{P} }\)

\(\large{ v =  d \; t }\)
