I am attending an online college with virtually no contact with peers or professors. Accreditation and scheduling make it the best choice for me. However, I find that I deeply miss the ability to discuss concepts and bounce ideas off p&p. Hence, I find myself here in the hope that I can find...
Homework Statement
I believe there is some kind of glitch in my Interactive Physics program. The screen shot below is supposed to be the result of applying an 8N force at 30º above the horizontal, from the left. My knowledge(?) tells me that a portion of that 8N is going to be expended...
1. Do your senior year in Spain, not Australia. Exposure to a new culture and language will be invaluable.
2. You're a B+ student without doing any homework. Imagine what you could be if you actually WORKED at school.
3. Learn to budget!
OK, thanks.
Love this new resource too. Glad you guys are here. That's the only thing I have found so far that I don't like about online college, nobody to discuss things with in real time.
BTW, where's the link for the 20% discount on SciAm? I think I'd like to take advantage of that.
Doc, there is no vertical acceleration. And so I figured I must be screwing something up. According my admittedly limited understanding FN should be equal to FG. If things were as the program is showing me it seems to me the block should be sinking downward (due to FG) in addition to moving...
The diagram is a portion of a screenshot from an exercise in a program called Interactive Physics. The horizontal plane is a frictionless plane. The small block is just a 2kg mass. FN is Normal force and reads 9.807N. FG is Gravitational force and reads 19.613N. FT is the applied force from...
I am struggling with this one. The question is to explain why the gravitational and normal forces are not equal. And I'll be darned if I know why they aren't. Logic tells me they should be equal. The small block has a mass of 2kg. And multiplying that mass times the normal (9.8N) gives me...
