    Non-Uniform Circular Motion

    Uniform circular motion is an acceleration motion. Comment.

    STATEMENT -1 : In non - uniform circular motion acceleration of a particles is along the tangent of the circle . STATEMENT -2 : In uniform circular motion acceleration of a particle is zero . STATEMENT -3 : In no - uniform circular motion acceleration of a particle is towards the centre of the circle.
