Velocity in accelerated motion

v=v_0+at

Result unit: m/s

What it describes

In uniformly accelerated motion the velocity grows linearly with time.

v

velocity

[m/s]

v_0

initial velocity

[m/s]

a

acceleration

[m/s²]

t

time

[s]

In uniformly accelerated motion the velocity grows linearly — to the initial velocity we add the increment

at

Motion with constant acceleration. For free fall (starting from rest)

v=gt

A body has

v_0=5

m/s and accelerates at

2

m/s² for 3 s. Find the final velocity.

Substitution

v_0=5

a=2

t=3

Result

v=5+2\cdot3=11

m/s.
