Velocity displacement formula: vt? =v0？ +2ax. derivation process: according to the velocity formula: vt=v0+at, t=(vt-v0)/a, substitute the displacement formula x=v0t+ 1/2at? = v 0(vt-v 0)/a+ 1/2a[(vt-v 0)/a]？ =(vt？ -v0？ )/2avt？ =v0？ +2ax .

Velocity, acceleration and displacement formulas 1. Velocity formula:

For variable speed linear motion: v plane = s/t

For linear motion with uniform speed change: speed formula: vt = v 0+a * t.

2. Acceleration formula:

a=(vt-v0)/t

According to the velocity displacement formula vt*vt-v0*v0=2as.

a=(vt*vt-v0*v0)/2s

3. Displacement formula:

For variable speed linear motion: s=v flat *t

For uniformly varying linear motion:

Displacement formula: s=v0*t+a*t*t/2.

Velocity displacement formula vt*vt-v0*v0=2as

The calculation formula of speed is: speed = distance ÷ time, and the mathematical expression is: v = s/t.

V stands for speed, in m/s, s stands for distance, in m, t stands for time, in s.
