# Fundamental Physics/Motion/Linear motion

## 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 $s$ $s$ Time $t$ $t$ Speed $v$ ${\frac {s}{t}}$ Acceleration $a$ ${\frac {v}{t}}$ Force $F$ $ma$ Work $W$ $Fs$ Energy $E$ $F{\frac {s}{t}}$ ## 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 $s$ $h$ Time $t$ $t$ Speed $v$ ${\frac {h}{t}}$ Acceleration $a$ ${\frac {h}{t^{2}}}$ Force $F$ $mg$ Work $W$ $mgh$ Energy $E$ $mg{\frac {h}{t}}$ ## 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 $v$ $v=v_{o}+at$ Time $t$ $t$ Acceleration $a$ $a={\frac {\Delta v}{\Delta t}}$ Distance $s$ $s=(v_{o}+at)t$ Force $F$ $F=m{\frac {\Delta v}{\Delta t}}$ Work done $W$ $W=Ft(v_{o}+at)$ Energy $E$ $E=F(v_{o}+at)$
