what is centripetal force ?
Asked by ayushikas | 22nd Jan, 2010, 03:52: PM
Centripetal force is the force required for an object to move along a curved path.
For example, in Uniform Circular Motion, the speed is constant but the direction of velocity changes at each point and hence velocity itself changes.
A change is velocity means acceleration.
An acceleration means a force.
And this is the centripetal force, directed towards the centre.
