The modern physics survey chapters are at the back of the course, and that is where apologies are made for having made what appears to be blanket statements earlier in the course.

NoEinstein > You made a general statement that if something is generally accepted, then that is a sign that it is nearly certainly WRONG. Now you don't seem so sure. You don't want to disavow common math, but you are certainly willing to disavow common, grade school mechanics like Newton's 2nd law. And I want to point out again that this has nothing to do with the "dark ages of Einstein", since Newton's 2nd law has been around for 323 years! You've decided that all of physics since Galileo and Newton are the dark ages! Einstein has nothing to do with your complaint. PD

NE Then let me make sure we're talking about the same title, because Clarence E. Bennett has written the following: Physics Problems and How to Solve Them (1958, 1959, 1960, 1968, 1972, 1985) College Physics (College Outline Series) (1962, 1972) Physics Without Mathematics (College Outline Series) (1949, 1953, 1960, 1970) New Outline of First Year College Physics (1944, 1946, 1948) An Outline of First Year College Physics (College Outline Series) (1937, 1943) Physics (1952, 1954) First Year College Physics (1954) Descriptive Physics (1945) As you can see, it's important that I know more about the particular title you own. The ISBN is either in the frontmatter or is printed on the back of the paperback. It's a 10-digit number right next to the letters I-S-B-N. Can you do that, John? PD

That equation F=mv is not listed in most textbooks. When you can clearly identify which title you think DOES have that listed, then I can look for myself. As it is, since you obviously have problems reading an understanding a single sentence from beginning to end, I have my doubts. > > > > > On May 4, 1:07 pm, af...(a)FreeNet.Carleton.CA (John Park) wrote: > > > > PD (thedraperfam...(a)gmail.com) writes: > > > > On May 3, 10:07=A0pm, NoEinstein <noeinst...(a)bellsouth.net> wrote: > > > > >> Dear PD: =A0A thin "College Outline Series" book (that fits into the > > > >> bookcase behind my computer chair) entitled "Physics", by Clarence E > > > >> Bennett, states on page 19: "G. =A0Momentum and Impulse. =A0(1..) =A0Momen= > > > > tum > > > >> is defined as the product of the mass times velocity (mv)..." =A0The > > > >> letter F is used for momentum, because the equation defines forces.. =A0= > > > > =97 > > > >> NoEinstein =97 > > > > > Oh, good grief.
