Question

define motion, what do you understand by uniform and non-uniform motion. explain with example

Answer 1

Motion is a state of object in which an object is moved and not in rest.

Uniform motion is a motion in which an object moves with equal speed and at equal intervals.

Non-uniform motion is a motion in which a object moves at unequal speed and at unequal distances.

Brainliest pleaseeeeeeeeeeeeeeee.

Answer 2

$\large\sf \underline{Motion :- }$

$\orange\implies$Movement of any object from one position to another position with respect to the observer is called as Motion.

$\underline{\underline{\maltese\:\: \textbf{\textsf{Uniform Motion}}}}$

$\purple\implies$If an object is travelling with uniform motion, it is moving in a straight line at a constant speed.

For example:- when a car travels at a constant speed, the driving force from the engine is balanced by the resistive forces such as air resistance and frictional forces in the car's moving parts.

$\underline{\underline{\maltese\:\: \textbf{\textsf{ Non-Uniform Motion}}}}$

$\pink\implies$A body is said to be in a non-uniform motion if it travels unequal distances in equal intervals of time.

$\pink\implies$ Non - Uniform motion is also known as accelerated motion.

For Example :- Oscillation of pendulum, the motion of a train, a person jogging in the park etc.
