1. Distance: The total length traveled by an object.

2. Time: The duration it takes to travel that distance.

Formula:

Speed = Distance / Time

Example:

If a car travels 100 kilometers in 2 hours, its speed is:

Speed = 100 km / 2 hours = 50 km/h

Units of Speed:

* Meters per second (m/s)

* Kilometers per hour (km/h)

* Miles per hour (mph)

* Feet per second (ft/s)

Important Notes:

* Speed is a scalar quantity, meaning it only has magnitude (size) and no direction.

* Velocity is a vector quantity, meaning it has both magnitude and direction.

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

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