Question

what is meant by motion?​

Answer 1

Motion is the phenomenon in which an object changes its position over time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and time. ... One can also speak of motion of images, shapes and boundaries.

Answer 2

$\large\underline\mathrm{There \: type \: of \: motion:-}$

$\large\underline\mathrm{1. \: One \: dimensional \: motion}$

• One co - ordinate is varying with time then motion of the body is known as the one dimensional motion.

Eg:- motion of any body on a straight line.

$\large\underline\mathrm{2. \: Two \: Dimensional \: motion:-}$

• Those motion in which any two co - ordinate is in which any two co - ordinate is varying with time then it is called the two dimensional motion.

Eg:- circular motion, projectile motion.

$\large\underline\mathrm{3. \: Three \: Dimensional \: Motion:-}$

• If all the three co - ordinate varying with time then it called the three dimensional motion.

Eq. Motion of a bird.
