Average speed is a measure of how fast an object is moving on a path over a given distance. It tells us how quickly it covers a specific distance in the total time taken to travel that path. Calculating average speed involves dividing the total distance travelled by the total time taken.
Key Formula:
Average Speed (Average Speed = Distance ÷ Time)
Let's break it down:
Distance: The total distance travelled by the object. It can be measured in various units like metres, kilometres, or miles, depending on the context.
Time: The total time taken to cover the distance. It can be measured in the same units as distance, or it can be provided as a time interval (e.g., 10 minutes).
Example:
Imagine a car travelling from point A to point B on a road.
Distance travelled = 200 metres
Time taken = 10 minutes
Substituting these values into the formula, we get:
Average Speed = 200 ÷ 10 = 20 m/s
This means the car was travelling at an average speed of 20 m/s during that journey.
Additional Points:
Average speed can be expressed in different units, like km/h, mph, or cm/s, depending on the context.
It's important to consider the units of distance and time when calculating average speed.
Average speed is a scalar quantity, meaning it has only magnitude and no direction
