What is Velocity?
Velocity is a measure of both speed and direction. Imagine two cars:
* Car A: Drives at 60 mph due east.
* Car B: Drives at 60 mph due north.
Both cars have the same speed (60 mph), but they have different velocities because their directions are different.
How to Determine Same or Different Velocity:
1. Speed: Are the objects moving at the same rate? If their speeds differ, their velocities are different.
2. Direction: Are the objects moving in the same direction? If their directions are different, their velocities are different.
Examples:
* Same Velocity: Two trains on the same track traveling at 50 mph in the same direction.
* Different Velocity: A bird flying 20 mph north and a plane flying 500 mph south.
Key Points:
* Constant Velocity: An object has constant velocity if its speed and direction remain unchanged.
* Changing Velocity: An object has changing velocity if either its speed, direction, or both are changing.
* Acceleration: A change in velocity is known as acceleration.
