Find the expression of centripetal acceleration

Answer 1

Acceleration acting on the object undergoing uniform circular motion is called centripetal acceleration.Expression : Consider a particle of mass m, moving with a constant speed v and uniform angular velocity \si , on a circular path of radius r with centre at O.

Answer 2

$\huge{\mathcal{\underline{\underline{\pink{AnsWer:-}}}}}$

Centripetal acceleration of a particle revolving in a circle of radius 'r' with velocity 'v' is given by ,

$\large\rm\bold{\underline{\boxed{a_c\:=\:\frac{v^2}{r}}}}$

$\huge\tt{\underline{\underline{\green{Additional\:Information:-}}}}$

❃ Centripetal Accleration is the acceleration which is required to keep the particle revolving in circular motion . The direction of centripetal acceleration is directed towards the centre

❃ SI unit of Centripetal acceleration is m/s²

CGS unit of centripetal acceleration is cm/s²

❃ Centripetal acceleration is also called as central acceleration (or) Radial Acceleration .
