The movement of the Sun and the Earth
Look at the sky , and you will notice that the Sun rises from the east and sets from the west , The sunrise and the sunset do not occur due to the rotation of the Sun , but it occurs due to the rotation of the Earth around itself ( its axis ) .
This phenomenon is called the apparent movement of the Sun , where it takes different apparent orbit from the east to the west , The movement of the shadow of the fixed bodies is due to the apparent movement of the Sun .
The rotation of the Earth
The Earth is one of the planets , where we can live because it contains the air , the food and the water , The Earth consists of two hemispheres ( northern hemisphere and southern hemisphere ) , The Earth rotates around itself and rotates around the Sun .

Would a brick or feather fall faster, Physics
Physics is the study of the basic principles that govern the physical world around us. We'll start by looking at motion itself. Then, we'll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you'll need a solid understanding of algebra and a basic understanding of trigonometry.

Learn about Planet Earth
The earth is the third planet from the Sun in our solar system.
It is the fifth largest of the eight planets in our solar system and the only planet that supports life. The earth is home to millions of species including us…humans! Scientists believe that the earth is the only planet to have life on it. The earth is about 12,756 Km or 7,926 miles in diameter.

Isaac Newton
Sir Isaac Newton PRS (/ˈnjuːtən/;[6] 25 December 1642 – 20 March 1726/27[1]) was an English mathematician, astronomer, and physicist (described in his own day as a "natural philosopher") who is widely recognised as one of the most influential scientists of all time and a key figure in the scientific revolution. His book Philosophiæ Naturalis Principia Mathematica ("Mathematical Principles of Natural Philosophy"), first published in 1687, laid the foundations of classical mechanics. Newton also made seminal contributions to optics, and he shares credit with Gottfried Wilhelm Leibniz for developing the infinitesimal calculus.
