I'm actually reading a book by a 20th century American, hence the use of pounds and poundals. It truly is confusing, I'm most certain he sometimes refers to mass when he uses the word "weighs" so it is almost impossible for me to know what he is truly saying/asking. His section on Newton is the...
Thanks TheAbsoluTurk! I was so confused by the fact that the book states that pounds is the mass and poundals is the weight, such that when he stated pounds of weight I was unsure which of the two he meant.
This makes sense now: I find out the mass of the automobile on Earth and then find the...
Hi,
I'm reading a book and one of the questions asks: how much force is required to give an object weighing 3000lb an acceleration of 12ft/sec2?
I calculated this as F=3000x12=36,000pdl. The answer given is "1125 force" (36,000/32). Why is this? Why isn't it just 36,000pdl?
I found that those values came close to 1, I suppose there is a number of infinite decimal places that satisfies the equation then.
Ok, so it is possible to find roots that satisfy the above equation. When you calculated the above did you first convert the factors into their second degree form...
If x=-1 then (-1+1)(-1+1) would equal 0 rather than 1, but I see your point: If I had (x+2)(x+3)=1 it would be impossible to solve since there is no number (x+2)=1/(x+3) or (x+3)=1/(x+2) but there is a number where (x+2)=0 and (x=3)=0. Would you mind showing me the mathematical proof that the...
Hi,
This is perhaps the most rookie question to Mathematics that one could ask, but I have searched for information on the question and found only one source which contained an answer. The answer was that it is because otherwise we wouldn't know what the value of either of the factors is. I...
Some may argue that his lectures aren't suitable for beginners to physics? Would you agree? I wish to start from the beginning. His lectures are certainly on my list, having read the first few pages of the first book I found the book very compelling.
Money is to some extent an issue, but it would be nice to know books which you recommend. When I see the prices I'll determine how much of an issue it is :)
It covers a wide range of areas of mathematics, especially paired with Advanced Engineering Mathematics (the continuation of the book).
Feynman lectures seem to be the closest thing to what I would like, but I was hoping for something like University Physics with Modern Physics, but better.
It's not necessary that it be non-mathematical. I can't imagine the subject could be explained very well without mathematics, but it would be preferred to have detailed discussions of each topic.
Hi,
Does anyone know of a Physics textbook that covers a very broad range of topics from basic to graduate level, contains detailed explanations, and perhaps exercises (although this latter is not necessary)? Hence, a complete Physics textbook, like what "Engineering Mathematics" is to...
