A rocket motor is a propulsion system that generates thrust to propel a rocket or spacecraft by expelling mass at high speed, typically through the combustion of propellants. It operates based on Newton's third law of motion, where the action of expelling gas results in a reaction that pushes the rocket in the opposite direction. Rocket motors can be classified into solid, liquid, and hybrid types, depending on the state of the propellant used. They are essential for launching vehicles into space and for maneuvering in various space missions.

Nighttime occurs because the Earth rotates on its axis, causing different parts of the planet to face away from the sun. When a location is turned away from the sun, it experiences darkness, while the side facing the sun is illuminated. This cycle of day and night is a natural result of Earth's rotation and its position relative to the sun. During nighttime, we cannot see the sun directly, but it is still providing light to the other side of the planet.
