class 11th physics: motion in a straight line

Average speed is a measure of the total distance traveled divided by the total time taken to travel that distance. It is a scalar quantity, meaning it only has magnitude and no direction.

To calculate average speed, you use the formula:

Average Speed =Total Distance /Total Time

For example, if a car travels 300 kilometers in 5 hours, its average speed would be:

Average Speed = 300 km /5 hours =60 km/h
This means that, on average, the car traveled at a speed of 60 kilometers per hour during the journey. The concept of average speed doesn't take into account the variations in speed during the trip; it simply provides an overall rate of motion for the entire distance covered.
