The normal is always perpendicular to friction and friction is equal to the coefficient of friction times the normal. another thing which might help is that the y component of the tension vector plus the normal is equal to mg(force on sled by earth)

the object would have its own gravity, and if its mass was the same as Earth using Newtonian gravity it would have the same gravity as Earth and the force between them would be twice what it would have been with just Earth (and some arbitrarily small object). the two objects would accelerate to...

I have eliminated Ithaca because I visited and was very unimpressed I also visited RIT and while it is statistically not as prestigious as the others I am very impressed by it as a whole and I would not mind going there. tomorrow I am visiting RPI if anyone knows anything specifically...

There is a book that I have been using called Calculus: An Intuitive and Physical Approach https://www.amazon.com/dp/0486404536/?tag=pfamazon01-20 It has been a great source, it teaches calculus by using physics and physical concepts so that as you work through it the calculus comes...

The UNC on my list is UNC Chapel Hill do you know the state of their physics and math department? I have gotten conflicting messages. thanks for help everyone

thanks

I want to be a physics major and I am very interested Astrophysics as a final career path. However recently, after reading a few books about it I have become interested in Information Theory and the prospect of Quantum Computers. I have a very strong Math, Physics, and Computer Science...

I live in North Carolina and am going into senior year of high school and am looking to major in Physics for college with the end goal of either doing something in Cosmology or Astrophysics and am open to Condensed Matter physics. I have a list of schools that I have narrowed it down to. If...

where is that video i could not find it?

thanks

This may have been posted somewhere else but, I would like to know. How do LQG theorists reconcile the fact that the universe is expanding at an accelerating rate, and the LQG prediction of the big bounce. Also I have heard that they say the universe is still expanding because of inertia from...

I did not know that Carl Sagan thought of that propulsion system. I thought of that myself a year ago.

i recently heard of technology that is still in research and development phase. this is a synthetic material similar to plastic, but biobased that expands and contracts with electric pulses. the following is from Science Daily article 'Biobased Plastic Flexes Its Muscle' i could be...
