I writing a paper in physics. Its has the theme " A day without friction". I was thinking about what would be a huge affect of no friction on a global scale. Then I thought about the layers of rock that are under the surface and are constantly going under and over each other. I though about the continental drift the formed our current continents. If there was no friction wouldnt these things go crazy and start moving uncontrollably and make the continents start drifing into each other causing disater? Wouldnt the earth get really cold because that friction under the ground creates the heat that is in the earths center? Would that mess up orbit? Or would gravity have to stop too. Tell me what you think would be the biggest effect of no friction on a global scale.

As we all know, everything that exists ( i.e can be seen, felt ) has 3 dimensions, but can anything exist for no time? No. That means time is the fourth dimension as nothing can exist for no time!!!

Can we get e/m ratio theoratically? where e=charge on electron m=mass of electron I am asking this because Sir J.J.Thomson performed an exepriment for that.

Im refering to the theory around the hadron collider...im not sure if I am remembering this right....

when two particles collide they hope to catch a graviton? What is a gravitron and what does it have to do with the string? And how do they see it?

Or does the tool release stresses that then distort the image & cannot be corrected?

So when we look out we are looking back into time and cannot see further than the age of the universe, correct?
example(if the universe is 14 billion years old we could only see 14 billion light years away)(because any further and the light would not have the time to reach us)
Why dont we see the edge? is it because light, even light a huge number of sources does not travel that far? (less than halfway across the universe)

A subway train starts from rest at a station and accelerates at a rate of 1.60 m/s}^{2} for 14.0 s. It runs at constant speed for 70.0 s and slows down at a rate of 3.50 m}/s}^{2} until it stops at the next station. Find the total distance covered.

Two runners start simultaneously from the same point on a circular track of length 217 m and run in the same direction. One runs at a constant speed of 5.50 m/s and the other at a constant speed of 6.00 m/s. When will the fast one lap the slower one? How far from the starting point will the slower one have run? How far from the starting point will the fast one have run?

For my high school physics class we are required to do an "A" project per quarter to recieve an A in the class. I would really like to do something with food. I saw somewhere that you could make a jello cake for a cell, that is a great idea for biology. However, I don't think that will work for physics. Any ideas. If I can't do food, I am interested in doing a video, but I am unsure of the topic I could use. the title of the class is Physics-Mechanics. I haven't learned much yet, and I have a feeling I will have to be teaching myself the basic ideas of this. Please help me.

An airplane travels a distance 288 m down the runway before taking off. if it starts from rest, moves with constant acceleration, and becomes airborne in time 8.50 s, what is its speed when it takes off?

I was wondering how you would apply E=MC^2 to a physics problem. The problem is asking for the maximum mass of a rocket that can reach an altitude of 345 km. It can convert 1 g matter into thrust energy by E+MC^2. I admit this is a homework problem so you don't have to give me the answer but just simply how to start working it. My teacher did not go over this and I can't find it in my book. Thank you in advance.

I am asking whether the Tesla Coil's energy output contains any energy lent to it by the mass of the coil itself?

When we think of a black hole, we picture in our minds eye a two diminsional plane with a funnel shaped hole. This veiw is limiting especially if a black hole is three dimensional entity similar to our sun.

In earlier times people thought the sun was actually a large flood lamp like the ones they use in hollywood. (no doubt some people who actually still believe the sun is a large flood lamp will have difficulty resisting this question.)

If you think black holes exist as three dimensional entities attracting/emitting matter omnidirectionally, please share your veiw.

Right now Light travels at about c = 300,000km/s Our movement is so slow relative to this speed that the effects of Einstein's theory of relativity are not noticable. But what would the world be like if c was 1000 miles/hour instead? Ignore the fact that earth is rotating that fast and moving in space much faster, I want some ideas of what affect it would have on everyday life on earth. Have fun racking your brain on this one, lol.
