Question

Write the equation of velocity of an object moves  in circular path
class 9 pleease be fast​

Answer 1

The rate of change of displacement of a body with the passage of time is known as velocity of the body. Velocity of an object is measured in meter per second in SI units. So, velocity is equal to displacement divided by time taken.

$speed = \frac{displacement}{time}$

two formulas are mainly applied which is :-

for linear motion

$a = \frac{v - u}{t}$

for circular motion

$v = \frac{2 \: \pi \: r}{t}$

where,

a= acceleration

v = final velocity

u = initial velocity

t = time

r = radius of the circular object around which the object is revolving

hopefully this will help you better !!!!!

Answer:

The rate of change of displacement of a body with the passage of time is known as velocity of the body. Velocity of an object is measured in meter per second in SI units. So, velocity is equal to displacement divided by time taken.

speed = \frac{displacement}{time}speed=

time

displacement

for linear motion

a = \frac{v - u}{t}a=

t

v−u

for circular motion

v = \frac{2 \: \pi \: r}{t}v=

t

2πr

where,

a= acceleration

v = final velocity

u = initial velocity

t = time

r = radius of the circular object
