Circular path: The object's trajectory is a circle.
Constant speed: The object's speed doesn't change as it moves along the circle.
Important Note: While the object's speed is constant, its velocity is not. Velocity is a vector quantity, meaning it has both magnitude (speed) and direction. Since the object is changing direction constantly in circular motion, its velocity is always changing, even though its speed remains the same.
Examples of Uniform Circular Motion:
* A car driving around a roundabout at a constant speed.
* A satellite orbiting the Earth at a constant speed.
* A ball on a string being swung in a circle at a constant speed.
* A spinning record on a turntable.
Key Characteristics:
* Centripetal acceleration: The object experiences an inward acceleration towards the center of the circle, called centripetal acceleration. This acceleration is what keeps the object moving in a circle.
* Centripetal force: A force is required to produce this centripetal acceleration. This force always acts towards the center of the circle and is called the centripetal force.
