* Speed is the rate at which an object covers distance. It only tells us how fast the object is moving.
* Velocity is speed with a direction. It tells us how fast the object is moving and in what direction.
Example:
Imagine a car traveling at 60 miles per hour on a straight highway. Here's the breakdown:
* Constant speed: The car maintains a constant speed of 60 miles per hour.
* Constant velocity: Since the car is traveling in a straight line, its direction doesn't change. Therefore, its velocity is also constant at 60 miles per hour in the direction of the highway.
Example of constant speed, but NOT constant velocity:
Imagine the same car traveling at 60 miles per hour around a circular track.
* Constant speed: The car maintains a constant speed of 60 miles per hour.
* Non-constant velocity: Even though the speed is constant, the car's direction is constantly changing as it moves in a circle. Therefore, its velocity is not constant.
Key takeaway: For an object to have constant velocity, it must move at a constant speed in a straight line.
