Question

Define non-uniform motion.
Define uniform motion.​

Answer 1

Answer:

When a body moves along a straight line with uniform speed or steady speed is called Uniform motion.

When a body moves along a straight line but with variable or change in speed is called non-uniform motion.

Answer 2

$\underline{\underline{\sf{\green {Uniform Motion }}}}$

if a body cover equal distance in equal interval of time in a straight line then its motion is said to be uniform motion .

$\underline{\underline{\sf{\green {Non - Uniform Motion }}}}$

if a body cover unequal distance in equal interval of time then its motion is said to be non uniform motion .

Motion :- an object is said to be in motion if its position changes continuously with respect to a fixed reference point called origin.

Speed :-

• > speed of a body is defined as distance travelled by its per unit time.

• > if a body cover a distance 's' in time 't' , then speed is mathematically expressed as

$speed = \frac{distance}{time} = \frac{s}{t}$

• > speed is a scalar quantity and its SI unit is m/s . A body moving in uniform motion is said to have uniform speed .

Velocity :-

• > velocity of a body is defined as its displacement per unit time.

• > $velocity \: = \frac{displacement}{time}$

• > velocity is a vector quantity and its SI unit is same as off speed m/s . velocity can be positive , negative or zero depending upon displacement of body.
