Question

what do you understand by motion in one ,two,three dimensional with example
​

Answer 1

$\huge\bigstar\:$$\Huge\tt\underline\blue{ANSWER}$

Motion in three dimensions: The motion of a body is said to be in three dimensions or three dimensional motion if it moves in space. In this type of motion three position co-ordinates are required to describe the position of the particle.

Answer 2

Explanation:

MOTION IN ONE DIMENSION - DEFINITION

If a particle is moving in a single direction throughout its journey then it is said to be moving in one dimension. For example, an ant moving along X-axis. Motion is described in terms of displacement (x), time (t), velocity (v), and acceleration (a). Velocity is the rate of change of displacement and the acceleration is the rate of change of velocity.

MOTION IN TWO AND THREE DIMENSION - LAW

Motion in two dimension: Motion in a plane is described as two dimensional motion.

Example: An ant moving on the top surface of a desk is example of two dimensional motion. Projectile and circular motion are examples of two dimensional motion.

Motion in three dimension: Motion in space which incorporates all the X, Y and Z axis is called three dimensional motion.

Example: Movement of gyroscope is an example of three dimensional motion.
