What is Speed?

Speed is a measure of how fast something is moving. It tells you how much distance is covered in a given amount of time.

How is Speed Made?

Speed isn't "made" in the sense of creating something new. It's a *calculated* quantity that arises from two fundamental concepts:

1. Distance: The total length of the path travelled. (Think of it as how far something goes)

2. Time: The duration of the movement. (Think of it as how long it takes)

The Formula:

Speed is calculated using the following formula:

Speed = Distance / Time

Example:

Imagine a car travels 100 kilometers in 2 hours. To find its speed:

* Speed = 100 kilometers / 2 hours

* Speed = 50 kilometers per hour (km/h)

Key Points:

* Units: Speed is always expressed in units of distance per unit of time (e.g., kilometers per hour, miles per hour, meters per second).

* Average vs. Instantaneous:

* Average speed is the total distance traveled divided by the total time taken.

* Instantaneous speed is the speed at a specific moment in time.

* Velocity: Velocity is similar to speed but also includes the direction of movement.
