Definition

Linear motion represents motion of any object follows a straight line path without changing it's direction . For examples, Horizontal linear motion , Vertically linear motion , Inclined linear motion

Horizontal linear motion

Horizontal linear motion represents any motion that travels in straight line horizontally. The chracteristics of Horizontal linear motion are listed in the table below

Distance	${\displaystyle s}$	${\displaystyle s}$
Time	${\displaystyle t}$	${\displaystyle t}$
Speed	${\displaystyle v}$	${\displaystyle {\frac {s}{t}}}$
Acceleration	${\displaystyle a}$	${\displaystyle {\frac {v}{t}}}$
Force	${\displaystyle F}$	${\displaystyle ma}$
Work	${\displaystyle W}$	${\displaystyle Fs}$
Energy	${\displaystyle E}$	${\displaystyle F{\frac {s}{t}}}$

Vertical linear motion

Vertical linear motion represents any motion that travels in straight line vertically . The chracteristics of Vertical linear motion are listed in the table below

Distance	${\displaystyle s}$	${\displaystyle h}$
Time	${\displaystyle t}$	${\displaystyle t}$
Speed	${\displaystyle v}$	${\displaystyle {\frac {h}{t}}}$
Acceleration	${\displaystyle a}$	${\displaystyle {\frac {h}{t^{2}}}}$
Force	${\displaystyle F}$	${\displaystyle mg}$
Work	${\displaystyle W}$	${\displaystyle mgh}$
Energy	${\displaystyle E}$	${\displaystyle mg{\frac {h}{t}}}$

Inclined linear motion

Inclined linear motion represents any motion that travels in straight line at an inclined angle . The chracteristics of Inclined linear motion are listed in the table below

Speed of motion	${\displaystyle v}$	${\displaystyle v=v_{o}+at}$
Time	${\displaystyle t}$	${\displaystyle t}$
Acceleration	${\displaystyle a}$	${\displaystyle a={\frac {\Delta v}{\Delta t}}}$
Distance	${\displaystyle s}$	${\displaystyle s=(v_{o}+at)t}$
Force	${\displaystyle F}$	${\displaystyle F=m{\frac {\Delta v}{\Delta t}}}$
Work done	${\displaystyle W}$	${\displaystyle W=Ft(v_{o}+at)}$
Energy	${\displaystyle E}$	${\displaystyle E=F(v_{o}+at)}$
