1. Velocity is a vector quantity: This means it has both magnitude (speed) and direction.
2. Speed vs. Velocity:
* Speed is the rate at which an object moves (e.g., meters per second). It only tells you how fast something is going.
* Velocity tells you both the speed *and* the direction of movement.
Here's how to figure out which object has the highest velocity:
1. Compare their speeds: The object with the highest speed will be moving the fastest.
2. Compare their directions: If the objects are moving in different directions, even if they have the same speed, their velocities will be different.
Example:
* Object A: Speed = 10 m/s, Direction = East
* Object B: Speed = 5 m/s, Direction = West
* Object C: Speed = 10 m/s, Direction = North
In this example:
* Object A has the highest speed (10 m/s).
* Object C has the highest velocity because it's moving the fastest *and* in a different direction than Object A.
To determine the highest velocity, you need to know both the speed and direction of each object.
Note: If two objects have the same speed and direction, they have the same velocity.
