Space Travel and Exploration

Rockets used to launch spacecraft operate based on Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction. When a rocket engine burns fuel, it expels gas at high speed in one direction, creating thrust that propels the rocket in the opposite direction. This thrust must overcome Earth's gravity and atmospheric drag to lift the spacecraft into space. Additionally, rockets are designed to carry both fuel and oxidizer, enabling them to function in the vacuum of space where oxygen is not available.
