Scalar quantities (m, K, t) and the magnitudes of vector quantities (F, g, v) are written in an italic, serif font — except for Greek symbols (α, τ, ω), which use a roman serif font. Mathematical symbols use a roman, serif font (½, +, √, cos) — except when they are applied to calculations with units.

The symbol a stands for the acceleration of the object. And the symbol v stands for the velocity of the object; a subscript of i after the v (as in vi) indicates that the velocity value is the initial velocity value and a subscript of f (as in vf) indicates that the velocity value is the final velocity value.
In symbols, average velocity is \[\bar{v}=\frac{Δx}{Δt}=\frac{x_f−x_0}{t_f−t_0} \nonumber.\] The SI unit for velocity is m/s. Velocity is a vector and thus has a direction. Instantaneous velocity \(v\) is the velocity at a specific instant or the average velocity for an infinitesimal interval.

The integral of acceleration over time is change in velocity (∆v = ∫a dt). The integral of velocity over time is change in position ( ∆ s = ∫ v dt ). Here's the way it works.
9 lut 2012 · Speed, distance and time can be calculated using a magic triangle. D (the distance) goes in the top of the triangle, S (speed) goes in the bottom left of the triangle, and T (time) goes in the bottom right of the triangle. Read on for my full explanation!
