Answer 1

‡Answer‡

Centripetal acceleration is the acceleration experienced while in uniform circular motion. It always points toward the center of rotation. It is perpendicular to the linear velocity and has the magnitude. The unit of centripetal acceleration

formula ࿐

✯✯✯✯_________________________✯✯✯✯✯

Centripetal acceleration ac is the acceleration experienced while in uniform circular motion. It always points toward the center of rotation. It is perpendicular to the linear velocity v and has the magnitude ac=v2r;ac=rω2 a c = v 2 r ; a c = r ω 2 .

Answer 2

Answer:

$\huge\color{blue}\boxed{\colorbox{black}{♡Answer♡}}$

In circular motion centripetal force is perpendicular to velocity. Also if the particles decrease or increase their speeds in circular motion then acceleration is generated which deviates the net acceleration from pointing towards the centre. Formula used: a=v2r.
