1. Circular Motion:
* Imagine a car driving around a circular track at a constant speed. Even though the car maintains a steady speed, its velocity is constantly changing because its direction is changing. Velocity is a vector quantity, meaning it has both magnitude (speed) and direction.
2. Uniform Circular Motion:
* Think of a satellite orbiting the Earth at a constant speed. The satellite's speed stays the same, but its velocity is constantly changing as it moves in a circular path. The direction of its velocity is always tangential to the circle.
3. Object Moving in a Curved Path:
* Imagine a ball thrown horizontally across a room. The ball's speed might be relatively constant, but its velocity is changing as it follows a curved path due to gravity.
4. Object Bouncing Off a Wall:
* Consider a ball bouncing straight back after hitting a wall. The ball might rebound with the same speed, but its velocity has changed because its direction is reversed.
In essence, any object moving in a curved path, even at a constant speed, will have a changing velocity because the direction of its motion is changing.
