Speed is the measure of how quickly an object moves from one place to another. It is a scalar quantity, which means it only has magnitude and not direction. The formula to calculate speed is:
Speed = Distance / Time
Where:
Here are some key concepts to remember about speed:
There are different units used to measure speed:
Let's go through an example of calculating speed:
If a car travels 100 kilometers in 2 hours, the speed of the car can be calculated as:
Speed = 100 km / 2 h = 50 km/h
Speed is an important concept in understanding how objects move in the world around us. By knowing the speed of an object, we can better understand and predict its motion.
