    All Possible Forces Known To Man

    In class we only covered the very basic; skimmed the surface. So to the best of my knowledge, the normal force of the Earth of the rock and the force due to gravity? I have no idea but I read somewhere that there would be a buoyant force on it from the atmospheric pressure of air on it?

    All Possible Forces Known To Man

    If a stone with a net force of approximately 0 sat on the surface of the Earth where it was perfectly level, what are ALL of the possible forces acting upon the stone known to man?

    Rising Physicist: Preparing for AP Physics & College

    Could you please elaborate on how AP Biology will be revamped, if you know. To clarify what I was implementing on whether or not taking AP stats vs AP bio will be better for my path towards taking Quantum Physics; I understand that quantum physics is based on probability and randomness (please...

    The price is quite heavy, but if you really do recommend it, I would be glad to invest towards reading the book. You have mentioned that there ARE errors, but are they small enough to be negligible? The book description states, "Now, we are reintroducing the printed books to the trade, fully...

    One force or two forces in Newton's third law?

    Ah, well my assumption was derived from the notion that Earth was a perfect sphere, which I now understand is wrong. Thank you for clarifying. Would you mind enlightening me on my post under the 'Academic Guidance' section? Thanks.

    One force or two forces in Newton's third law?

    Sorry, I'll clarify. Every object on EARTH, will have a force due to gravity that always point to the center of the Earth's mass.

    One force or two forces in Newton's third law?

    I want to clarify what he is saying. Normal forces are perpendicular to wherever the contact is between two objects. The force due to gravity is always pointing towards the center of the Earth, so for example, If a stone sat still on an elevated hill, the force due to gravity and normal forces...

    Rising Physicist: Preparing for AP Physics & College

    I am currently a junior in high school taking Pre-AP Physics, classical mechanics (pre-requisite for AP Physics, still classical mechanics). I chose to take this class because I had SOME interest in learning about the physical world and how it works. I'm exactly one semester into the class and I...

    Applying Newton's Laws and solving multiple object system question

    Homework Statement A 3.00-KG mass and a 10.0-KG mass are attached to opposite ends of a massless cord which is strung over a frictinoless pulley. a) What is the acceleration of the two-mass system? b) What is the tension in the cord? Homework Equations F = net forces Fg = force...
