Velocity measures how fast an object's position changes with respect to time. It includes both speed and direction.
Think about velocity as driving on a highway with multiple lanes. Speed alone tells you how fast you're going, but velocity also considers whether you're moving forward or backward in relation to your destination.
Speed (s): A scalar quantity that measures how fast an object moves without considering direction.
Acceleration (a): The rate at which velocity changes over time.
Displacement: The change in position of an object, taking into account both distance and direction.
