Velocity is a measure of how fast something is moving in a specific direction. It combines both speed and direction, which means that if a car is traveling at 60 miles per hour to the north, its velocity is 60 mph north. This is different from speed, which only tells us how fast the car is going without indicating where it is headed. Understanding velocity is important in many fields, such as physics, engineering, and even sports. For example, a football player needs to know their velocity to make accurate passes and runs. By knowing both speed and direction, they can improve their performance and strategy on the field.
