    Taking negative/positive square roots

    Oh, thank you. I was just accustomed to learning that if you perform one operation to one side of the equation, you have to do the equivalent on the other so I thought plus/minus square root on one side would mean I have to do exactly plus/minus square root to the other. I guess this is some...

    Taking negative/positive square roots

    Let's say that the variable 'x' is definitely some negative number. So if I wanted to solve: x^2 = 4 I get: \pm \sqrt{x^2} = \pm \sqrt{4} \pm x = \pm 2 I would have to take the positive value of 'x' and the negative value of '2' to make this true...is it okay to only take a positive square...

    What does the gravitational force of attraction mean?

    Mathematically, I think I sort of understand it... F_h = [G \frac{m_1}{r^2}] \cdot m_h and F_f = [G \frac{m_1}{r^2}] \cdot m_f F_h > F_f but F_h = m_h \cdot a_h \frac{F_h}{m_h} = a_h and F_f = m_f \cdot a_f \frac{F_f}{m_f} = a_f It seems that it actually turns out to be that...

    What does the gravitational force of attraction mean?

    So now I am wondering, why the force of gravity on an object has no effect on accleration, even though the force of gravity is pulling the hammer down much more strongly than it's pulling down on the feather? If I pull on a light object, I'd move it much faster than if I tried pulling a very...

    Is it worth watching Yale Fundamentals of Physics vids?

    Nano-Passion, I put a lot of effort into all of my classes, and since I never took Physics, Math is the only other subject you listed that I put any effort into. But I have taken other sciences such as Biology, Chemistry, Earth Science, Astronomy, etc. The latest Math class I took was...

    Is it worth watching Yale Fundamentals of Physics vids?

    Creel, the course is titled 'Calculus Physics' but I don't know at what pace they go at. I've only learned basic Calculus on my own, and probably have enough Calculus knowledge to the equivalent of half a semester's worth of first semester Calculus. I have some common sense such as finding the...

    Is it worth watching Yale Fundamentals of Physics vids?

    Because considering the average rate at which an average student is expected to learn a certain topic from an academic sequence, is in between each class which only lasts maybe 2-3 days, or the number of topics within a week, if you have irregular course schedules. If I enter an industry...

    What does the gravitational force of attraction mean?

    I meant what purpose does it have in mathematics and physics, since at first glance it doesn't seem to have any usefulness. I don't see how it can be applied to anything useful. So comparing the hammer and the feather: F_h = [G \frac{m_1}{r^2}] \cdot m_h and F_f = [G \frac{m_1}{r^2}] \cdot m_f...

    What does the gravitational force of attraction mean?

    I learned the formulas F = G \frac{m_1 m_2}{r^2} and F = m \cdot a and also saw mathematically that objects have the same gravitational acceleration and will fall down at the same rate, also demonstrated in a video by people that were on our moon, even though one object clearly has more force...

    Is it worth watching Yale Fundamentals of Physics vids?

    I'm not sure. In my younger years, I mostly studied because it was something I had to do, but somewhere along the way I thought of gaining information and understanding about a broad range of topics as a leisurely activity, and I studied out of fun. Eventually when I started high school, I...

    Is it worth watching Yale Fundamentals of Physics vids?

    Yes, I declared my major as Physics when I applied to the college I got accepted into No, I actually took a break from June until now to watch every single movie I hadn't seen in my high school years since I never had time to watch any because of my busy study schedule. Can't it be...

    Is it worth watching Yale Fundamentals of Physics vids?

    Yes, but all I did during high school up until last month when I graduated was study all day. I never had any friends so all I did was study pretty much every day, including the weekends. It doesn't seem like much fruition has come of it now that I'm starting college, which seems so different...

    Is it worth watching Yale Fundamentals of Physics vids?

    I am concerned because when school starts, I will have to learn all this stuff on my own and won't be able to keep up. We have class three times per week, so each topic we learn, I will have to know the topic inside and out within two days or I will be behind the class when we move on. I don't...
