Circular Motion - JSS2 Basic technology Lesson Note

Circular motion refers to the movement of an object along the circumference of a circle or a circular path. Circular motion is when an object moves in a path at a constant distance from a fixed point (centre).

Examples:

• The rotation of the Earth around the Sun.
• A stone tied to a string being swung in a circle.
• The wheels of a bicycle turn as it moves.

Applications:

• Mechanical Systems: Gears and pulleys in machinery use circular motion to transmit power and motion.
• Entertainment: Rides at amusement parks, like carousels and Ferris wheels, operate on principles of circular motion.
• Astronomy: The orbits of planets and satellites are examples of celestial bodies in circular motion.
