Question

Derive an expression for centripetal acceleration of a particle moving with uniform speed v along a circular path of radius r. Discuss the direction of this Acceleration

Answer 1

Answer:

Centripetal acceleration acts on the body moving in circular path towards the centre of the circular path.

centripetal ≈ centre seeking

Explanation:

if a particle moves in a circular path of radius r with uniform velocity v, then the expression for the centripetal acceleration(a) acting on the particle becomes:

a = v²/r = w²r

(where w is the angular velocity)
