* Uniform Velocity: Uniform velocity means an object moves at a constant speed in a constant direction.
* Seconds Hand Motion: The seconds hand moves in a circle. While its speed might be constant (covering the same distance in each second), its direction is constantly changing.
Think about it this way:
* The seconds hand is always moving, but its direction is constantly changing as it circles the clock face.
* Even though the hand covers the same distance in each second, its velocity (which includes both speed and direction) is not constant.
Instead of uniform velocity, the seconds hand on a watch demonstrates:
* Uniform speed: It moves at a constant rate.
* Non-uniform velocity: Its changing direction means its velocity is not constant.
