Answer 2

$\huge\mathfrak\pink{\underline{\underline{\underline{Motion\:along\:a\:straight\:line}}}}$

Everything in our world moves.Even stationary things such as your house move in relation to the sun or to other stars

The motion may be purely vertical,purely horizontal or slanted but it must be in straight line

For example :-when we try to locate an object in physics ,we will usually relate it to some sort of reference.The point is usually the origin ,the zero point of an axis

The simplest type of motion is the motion along the straight line .There are certain quantities that describe the motion numerically i.e distance and displacement where distance is a scaler quantity and displacement is a vector quantity
