Hi friends I know it's a very elementary question but i wat to know what centripital acceleration physically is? I mean, acceleration is something that results due to any force. In case of centripital acceleration, the force is centripital force (which e.g in case of car making turn is provided by tyres friction) and this force tends to bind the body to revolve around a center. Now, acceleration is basically, rate of change in velocity along a certain path or distance. And in case of circular motion the rate of change of angular velocity is angular acceleration, then what's centriptal acceleration?
