Question

define velocity and write down its mathematicale quuatlon​

Answer 1

$\huge\underline\bold\red{AnswEr}$

• ✓Velocity is the total displacement covered/taken in unit time .

• ✓ It is a venctor quantity.

• ✓It is expressed by 'v'.

• ✓It's SI unit is m/s.

• ✓the formula or expression of velocity (v) for an object covering a displacement s in time t will be: v=s/t.

Answer 2

Answer:

VELOCITY - Is the distance covered by an object in unit time in a particular dicertion.

It is vector quantity.

its unit is m/s

it can be negative , positive or zero

Method to find velocity = Displacement / time

More to know

Velocity can be changed by 3 ways

i) if distance changes .

ii) if direction changes.

iii) both distance and direction change.

Initial velocity is expressed as u.

Final velocity is expressed as V

Avg velocity = v + u / t

---- Rate of change of velocity is known as acceleration.

acc= v - u / t
