Linear Motion refers to any motion moving in a straight line without changing it's direction

Linear Motion with constant speed over time

Any Linear Motion that has constant speed at all time can be expressed as

v(t) = V

For any motion travels a Distance in Time caused by a Force has the following characters

Characteristics	Symbol	Mathematic Formula	Unit
Distance	${\displaystyle s}$	${\displaystyle s}$	m
Speed	${\displaystyle v}$	${\displaystyle {\frac {s}{t}}}$	${\displaystyle {\frac {m}{s}}}$
Accelleration	${\displaystyle a}$	${\displaystyle {\frac {v}{t}}}$	${\displaystyle {\frac {m}{s^{2}}}}$
Force	${\displaystyle F}$	${\displaystyle ma}$	kg ${\displaystyle {\frac {m}{s}}}$
Work	${\displaystyle W}$	${\displaystyle Fs}$	kg ${\displaystyle {\frac {m^{2}}{s}}}$
Energy	${\displaystyle E}$	${\displaystyle {\frac {W}{t}}}$	kg ${\displaystyle {\frac {m^{2}}{s}}}$

Linear Motion with changing speed over time

Any Linear Motion travels with different speed at different time v₁ at t₁ and v at t

The Change in Speed

${\displaystyle \Delta v=v-v_{o}}$

The Change in Time

${\displaystyle \Delta t=t-t_{o}}$

The ratio of Change in Speed over Change in Time gives the Accelerarion of the motion

${\displaystyle a={\frac {\Delta v}{\Delta t}}={\frac {v-v_{o}}{t-t_{o}}}}$

${\displaystyle \Delta v=a\Delta t}$

${\displaystyle v=v_{o}+a(t-t_{1})}$
