Have you ever wondered how something as heavy as an airplane manages to stay aloft in the sky?
Well, the shape of the plane's wing as it passes through the air creates lower pressure above the wing than beneath it. This pressure difference is what allows the wings to push upward and the plane to take flight. The faster the wing moves, the more lift is created, playing a key role in making sure air traffic stays on the up and up.
This is explained by Bernoulli’s Principle -This law of physics stipulates that the pressure of a fluid (liquid or gas) decreases as the speed of the fluid increases.

How does sun provide all the heat to the solar system?
The Sun creates energy through the nuclear fusion of hydrogen nuclei into helium.
What that means is that, since there is a huge amount of hydrogen in the core, these atoms stick together and fuse into a helium atom. This energy is then radiated out from the core and moves across the solar system!
