In Simple Terms
What it is
A rocket is a vehicle or device that moves by shooting out hot gases at high speed in the opposite direction. Think of it like a balloon letting out air—when you release the air, the balloon flies around. Rockets work the same way but on a much bigger and more powerful scale. They’re designed to travel fast and far, often into space.
Why people use it
Rockets help us do things that would otherwise be impossible, like exploring space or delivering satellites that power everyday technology. Without rockets, we wouldn’t have GPS for navigation, weather forecasts, or even some types of communication. They also help scientists study Earth and other planets, giving us valuable information about our universe.
Basic examples
Here are a few ways rockets make a difference in real life:
Space exploration: Rockets carry astronauts and robots to space, like the missions to the Moon or Mars.
Satellites: They launch satellites that help with TV signals, internet, and weather tracking.
Emergency response: Rockets can deliver supplies to remote areas or help monitor natural disasters from space.
Scientific research: They send telescopes and instruments into orbit to study stars, planets, and climate change.
Rockets might seem complicated, but at their core, they’re just powerful tools that help us reach beyond Earth and improve life on the ground.

Technical Details
What It Is
A rocket is a vehicle or device that generates thrust through the expulsion of high-speed exhaust gases, typically produced by the combustion of propellants. It belongs to the category of reaction engines, operating on Newton's Third Law of Motion ("for every action, there is an equal and opposite reaction"). Rockets are classified into subcategories such as ballistic missiles, space launch vehicles, and sounding rockets, depending on their purpose.
How It Works
Rockets function by burning fuel (propellant) in a combustion chamber, creating high-pressure gases that expand and are expelled through a nozzle at high velocity. This expulsion generates thrust, propelling the rocket forward. The technology relies on:
