* A car traveling at a steady 60 miles per hour on a straight highway. This is constant *linear* motion because the car is moving in a straight line at a constant speed.

* A Ferris wheel rotating at a constant speed. This is constant *circular* motion. Although the Ferris wheel is moving, its direction is constantly changing as it rotates. However, the speed remains constant.

* A planet orbiting a star at a constant speed in a circular orbit. This is another example of constant circular motion.

* The second hand of a clock. This is constant *angular* motion, as it moves at a steady rate around a circle.

Important Note: In real-world scenarios, true constant motion is difficult to achieve. There are always forces acting on objects, even if they are small, that can change their motion.
