1. Change in Speed: The most straightforward way is to simply increase or decrease the object's speed. A car accelerating from a stop increases its speed, and a ball rolling to a stop decreases its speed.
2. Change in Direction: Even if an object maintains a constant speed, changing its direction of travel alters its velocity. A car turning a corner at a constant speed still changes its velocity because its direction of travel is changing.
3. Change in Both Speed and Direction: The most common scenario is a change in both speed and direction. A ball thrown through the air is constantly changing both its speed (due to gravity) and its direction (following a curved path).
Remember: Velocity is a vector quantity, meaning it has both magnitude (speed) and direction. Any change in either speed or direction results in a change in velocity.
