Physics For Kids Welcome to our Physics section! We hope you enjoy learning about this really interesting subject. We are going to cover topics like Electricity, Magnets and how they work, and why things sink and float! Let's start exploring. Computer Fa
Smith (University of California, Berkeley), and The Hubble Heritage Team (STScI/AURA) Hubblesite Public domain According to the "Big Rip" theory, in a few billion years, a mysterious, permeating force known as "dark energy" will become so powerful that it could pull every ounce of Earth'...
Magnetism is a force of nature produced by moving electric charges. Sometimes these motions are microscopic and inside of a material known as magnets. Magnets, or the magnetic fields created by moving electric charges, can attract or repel other magnets, and change the motion of other charged ...

Comprehensive and meticulously documented facts about freedom of speech. Learn why the founders of the U.S. included free speech in the Bill of Rights, how courts have ruled in such cases, and much more.
3. Is it a directional force? Friction tends to act in the direction opposing motion. An object moving up experiences a frictional force in the downward direction and so on. Thus for an object to move, a force equal to the frictional force must be applied so that the two forces cancel ...
Mushrooms are becoming a huge force in the food economy. "Eighty-one percent of all restaurant menus include mushrooms,” and, “6% of all savory items on the menu include mushrooms. Independent restaurants are the highest users. However chains are the fastest growing.” That plus the growing...
The turbojet uses turbines to pull in and compress air before feeding it into the combustion chamber, whereas the ramjet relies on the force of the jet’s forward motion to force the air into the engine. Once you get past that, they serve the same purpose. A rocket engine, similar to...
