What is Kilometer per Hour ?

A Kilometer per hour (km/h) is a unit of measurement used to express speed or velocity. It indicates the distance of one kilometer traveled in one hour.

To break it down:
- 1 km/h means covering a distance of 1 kilometer in one hour.
- It is commonly used in countries that follow the metric system, such as most of Europe, Asia, and many others around the world.

In practical terms:
- Driving at 100 km/h on a highway means you would cover 100 kilometers in one hour if you maintained that speed consistently.
- For runners, running at 10 km/h means covering 10 kilometers in one hour.

Kilometers per hour are used widely in everyday situations to measure the speed of vehicles such as cars, buses, and bicycles, as well as for determining speed limits on roads and highways in metric-using countries. It provides a straightforward way to understand how fast something is moving over a specified distance.

Understanding km/h is important for drivers, athletes, and anyone interested in assessing or discussing speed in metric terms. It allows for easy comparisons and calculations related to travel times, distances, and speed-related safety considerations, particularly in regions where the metric system is standard.


What is Mach ?

Mach (M) is a unit used to measure the speed of an object relative to the speed of sound in the surrounding medium, such as air or water. When something travels at Mach 1, it is moving at the speed of sound. This speed can vary depending on factors like temperature and altitude because the speed of sound changes with these conditions.

For example, if an aircraft is flying at Mach 2, it means it is moving at twice the speed of sound. The term "supersonic" refers to speeds faster than Mach 1, while "subsonic" means speeds slower than Mach 1.

Mach numbers provide a convenient way to describe high-speed movements, especially in aerospace engineering and aviation. They help engineers and pilots understand how close an object is to breaking the sound barrier and encountering aerodynamic effects associated with supersonic flight.
