Watch on YouTubeVideoTypes of motion
- Rectilinear (translatory): along a straight line — falling stone, runner on straight track.
- Circular: along a circle — tip of a ceiling fan blade, stone tied to a string being swung.
- Rotational: spinning about its own axis — spinning top, Earth spinning, merry-go-round.
- Periodic (oscillatory): repeats in equal intervals — pendulum, swing, vibrating string.
- Random: no fixed pattern — butterfly flying, dust in air.
Objects can have MULTIPLE motions at once.
Example
A rolling car tyre — rotation (spins on axle) AND translation (moves forward). A washing machine drum — rotational (spins) AND oscillatory (shakes).
💡 Tip:Any wheel on a moving vehicle has BOTH rotational AND rectilinear motion.
