                               Friction is a critical part of everyday life to everyone. If there was no friction, you would keep on sliding when you go on a road, it would basically be icy roads the whole year. It can bring disadvantages though, it is also the thing that wears out tires faster, and it limits you from going farther in one run with gas, it makes you have to refill more. Even surfaces that seem smooth to the naked eye, such as wooden tables, they have many jagged and rough edges under a microscope. Those tiny bumps are the forces that stop the item from gliding across the surface of the table.
                                                                                                                                                      Even though we have a bunch of formulas that you use in high school to calculate force, motion and other matters such as velocity. We still aren't the best at taking 2 surfaces and saying what the friction is between them. to try and correct that and understand it better, Jay Weymouth, a scientist at the University of Regensburg slid a tiny tip made of tungsten against a surface of pure silicon crystals. A crystal is a solid material whose atoms are arranged in a very organized pattern, an example being a diamond. Jay Weymouth states that when you rub your hands together, it is still friction because you can even feel the interaction between millions of atoms, but he is trying to get it down to the smallest physical system they can reasonably measure, which is one atom against another.Image result for friction The experiment they are doing is claimed to have never been done before. The point of all this is to thoroughly understand how friction originates so that the properties of materials that are sliding can eventually be predicted and controlled. Overall, a better understanding of friction will help us develop, because then we will know how to give certain things more grip while loosen the grip on others.

I think that the next steps to this are to first, thoroughly understand how friction works, then apply that knowledge to some real world problems. Understanding friction will help us because then vehicles such as ATV's and other offroaders could be improved because they could have more grip on them. While at the same time, lessening the amount of friction present can also be beneficial, such as the tire example, if we understand friction better, we can figure out why tires get worn out so fast by friction and why cars go so slower than they can at their full potential due to friction.

Force and Motion in Concerts

Force and Motion Blog  By Amadi Clemens INTRODUCTION: Do you listen to Travis Scott? If so, you know of his most recent album AstroWorld has been on tour. One of his recent shows (in Oakland, California) he performed with a roller coaster. Crazy, right? It wasn’t like a full roller coaster that you see Six Flags. It’s like the Ring of Fire at Clementon Park. His ring ties into his theme park theme! PROS AND CONS: There are pros and cons that follow this event. A pro is that it was a fresh idea. I’ve seen amusement parks and rides in music videos but never live in concert. Another pro is that it was eye-catching and entertaining.. The main idea of a concert is that it is entertaining, this is going back to the idea of fresh. A con is that it’s very dangerous. Although thrilling, what if something goes wrong? What if it breaks? What if it stops mid-way in the year and he can’t rap anymore? Mechanical service would have to come and get him and that can ruin the concert. Another con, what

Chemical complexities that causes Saturn's rings to change planet’s atmosphere

Ayad Alhazmi 10/19/2018 Chemical complexities that causes Saturn's rings to change planet’s atmosphere New discoveries are made today on Saturn's rings by the Cassini space probe. Based on data from the final orbits of NASA's Cassini space probe shows the rings of Saturn. Some of the most amazing celestial objects in the universe are far more chemically complicated than was previously understood by scientist. When the Cassini space probe first gathered the information from 2017 and the signals of Cassini took scientist a long time to retrieve the information. Also knowing the astrophysicists are still studying it is beyond my reach. I will show you a quote by a professor of physics and astronomy Thomas Cravens. "Two things surprised me. One is the chemical complexity of what was coming off the rings -- we thought it would be almost entirely water based on what we saw in the past. The second thing is the sheer quantity of it -- a lot more than we originally expected.

The Earth is a very big Magnet Its North and South Poles are Highly Magnetic

The Earth is a very big Magnet     Its North and South Poles are Highly Magnetic   By: Alzahraa Alrubaiey Magnetism is the force exerted by magnets when they attract or repel each other. Magnetism is caused by the motion of electric charges. Earth has two geographic poles: the North Pole and the South Pole. They are the places on Earth's surface that Earth's imaginary spin axis passes through. Our planet also has two magnetic poles: the North Magnetic Pole and the South Magnetic Pole. The magnetic poles are near, but not quite in the same place as the geographic poles.   The Earth is a magnet that can interact with other magnets in this way, so the north end of a compass magnet is drawn to align with the Earth's magnetic field. Because the Earth's magnetic North Pole attracts the north ends of other magnets, it is technically the South Pole of our planet's magnetic field. A compass point north because all magnets have two poles, a north pole
