Understanding Circular Motion

When an object moves in a circle, it's constantly changing direction. This means it's accelerating, even if its speed stays the same. This acceleration is directed towards the center of the circle and is called *centripetal acceleration*.

The Key: Velocity is Tangential

The velocity of an object in circular motion is always *tangent* to the circle at that point. Imagine the ball at any point on the circle – if the string suddenly broke, the ball wouldn't continue in a circle, it would fly off in a straight line that's tangent to the circle at the point of the break.

Applying it to Your Scenario

Since the ball is swinging clockwise, and velocity is tangent to the circle, if the string breaks, the ball will fly off in a straight line *tangent* to the circle at the point where the string breaks.

Think about it like this:

* Clockwise rotation: Imagine a clock face – the ball is moving in the same direction as the hands of the clock.

* Tangential direction: The ball will fly off in the direction it was moving *at the moment the string breaks*.
