Imagine a world without cars. It might seem strange now, but there was a time when people relied solely on horses and carriages for transport. In 1885, Karl Benz, a German engineer, brought a revolution by inventing the first automobile. This car had a small engine and ran on petrol. Over time, cars became sleeker, faster, and more comfortable. They became an essential part of our lives, helping us travel quickly and conveniently. A car moves because of its engine. The engine burns fuel, and this energy is used to make the car move forward or backward. Today, engineers are inventing cars that run on electricity instead of petrol. They are designing self-driving cars that can navigate roads all by themselves. Cars are no longer just a mode of transport. They are a symbol of innovation, reflecting how far we've come and hinting at where we're heading.
