Answer:
Towards the center of the circle
Explanation:
When an object is moving in uniform circular motion, it means that it is moving at a constant speed in a circular path.
In order to follows a circular path, the particle must have a net force acting on it, that it makes it constantly changing direction - and therefore, causing an acceleration - and this force is called centripetal force.
The direction of this centripetal force is always towards the centre of the circular path.
The nature of the centripetal force is always different, depending on the situation. For instance: for a satellite orbiting the Earth in circular motion, the centripetal force is provided by the force of gravity. For a car moving round a curve, the centripetal force is provided by the force of friction between the tyres and the road.
The magnitude of the centripetal force is given by
where
m is the mass of the object
v is its speed
r is the radius of the circle
