Physics
Remember Physics is all about forces, magnetic fields and space. Most people think that it is to do with physical life because of words like Physio- therapy, Physical movement and many more. Unfortunately that is biology.
Forces:
A force is a type of element that causes things to move around. There are many different types of forces such as, push, pull, lift, throw and kick. Gravity pulls us down to the ground and increases our weight. For example, if you were to walk on the moon you would be lighter and you would be able to pick things up easier than on earth. But of course there must be somthing that pulls us up so the gravity dosen't squish us like pancakes. It is called lift. Every force must have an opposite force to balance it out or everything would go flying.
When you throw a ball, the forces that is pulling it down is Gravity

Space:
As you might know, space is an enormous thing. We live in space. Our Solar
System is only a tiny part of space. Most scientists call space the Universe.
There is a special name for these scientist and they are called astromonists.
They look through special telescopes called Radio telescopes, X ray telescopes,
Gamma ray telescopes, and Reflector telescopes. Radio telescopes detect noise
from radio wavelengths in space. X-ray telescopes are used to study mainly the
Sun, stars and supernovas. X-ray telescopes work better at very high altitudes
on the Earth's surface, like on top of a very tall mountain where the atmosphere is thinner.Gamma ray telescopes are best used at high altitudes like the x-ray telescopes. Gamma ray telescopes detect bursts of gamma rays.The Hubble Space Telescope is a reflecting telescope and is currently the largest space telescope there is. It is 43 feet long and weighs 24,250 pounds.
