* Velocity is a Vector: Velocity is a vector quantity, meaning it has both magnitude (speed) and direction.
* Angle Determines Direction: The angle of a velocity vector directly determines its direction.
* Changing Angle = Changing Direction: If the angle of the velocity vector changes, its direction changes.
Example:
Imagine a car traveling at a constant speed of 50 mph.
* Case 1: If the car is traveling due east, its velocity vector points east with a magnitude of 50 mph.
* Case 2: If the car turns and travels northeast, its velocity vector now points northeast, even though its speed remains 50 mph. The direction has changed because the angle has changed.
Important Note:
* Speed vs. Velocity: While the speed might remain constant, the velocity changes because it's a vector quantity.
