Question

obtain an expression for acceleration of a particle performing uniform circular motion

Answer 1

Explanation:

If an object moves in a circle it changes its velocity i.e. it is accelerating.

we know that centripetal force is given as

F = mv^2/r

now, as

F = ma

thus,

ma = mv^2/r

so, linear acceleration will be

a = v^2/r = w^2r
