The series follows Harry's journey as a young wizard who learns about his magical heritage on his eleventh birthday when he receives a letter of acceptance to attend Hogwarts School of Witchcraft and Wizardry. Harry discovers that he is famous in the wizarding world for surviving an attack by the dark wizard Lord Voldemort when he was just a baby. Voldemort's curse left a lightning bolt-shaped scar on Harry's forehead and killed his parents.
Throughout the series, Harry and his friends, Ron Weasley and Hermione Granger, face various challenges and uncover the mystery behind Voldemort's return to power. Harry is known for his courage, loyalty, and determination to fight against dark forces, despite the numerous obstacles he encounters. The books explore themes of friendship, bravery, the battle between good and evil, and the importance of choices.
The popularity of the "Harry Potter" series led to the creation of a successful film franchise, stage plays, merchandise, and an expansive Wizarding World franchise that includes spin-off books and movies like the "Fantastic Beasts" series.
A rocket works by expelling high-speed exhaust gases in one direction, which creates a corresponding force that propels the rocket in the opposite direction. This expulsion of gases is achieved through the combustion of rocket propellant in the rocket engine. The reaction gases are expelled through a nozzle at high speeds, generating thrust that propels the rocket forward.
Unlike an airplane, which requires air to generate lift, a rocket does not rely on atmospheric air for propulsion. Instead, it carries its own oxidizer along with the fuel, enabling it to operate in the vacuum of space where there is no air. This is why rockets are used to launch satellites, explore other planets, and conduct space missions.
