1. Change in Speed: The most obvious way to change velocity is to speed up or slow down. This directly alters the magnitude of the velocity.
* Example: A car accelerating from a stoplight increases its speed, thus increasing its velocity.
2. Change in Direction: Even if an object maintains a constant speed, it can still change its velocity by changing direction. This alters the direction component of the velocity.
* Example: A car driving around a curve at a constant speed is still changing its velocity because its direction is changing.
3. Change in Both Speed and Direction: Finally, velocity can change by combining changes in speed and direction.
* Example: A rocket launching into space not only increases its speed but also changes its direction, thus changing its velocity in both ways.
