Question

Derive the expression for centripetal acceleration.​

Answer 1

Answer:

Hence, vector form of centripetal acceleration is: →a=−ωR2(sinωt ˆi+cosωt ˆj) which shows that it's direction is towards the centre and along the string at every point of circular track. Hence centripetal acceleration is ωR2.

Answer 2

Answer:

Centripetal acceleration ac is theacceleration 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 .
