    How Is Heat Calculated from Friction Over Time?

    How does one calculate the heat generated by a force of friction with respect to time? Let's stick with constant mass and assume that we know everything but heat. Thanks for looking in, MJ

    Gravitational attraction and acceleration over time.

    To avoid an absurdly complex problem, let's assume that all these objects magically came into existence without any initial velocity or momentum.

    Gravitational attraction and acceleration over time.

    Suppose I have 2 bodies, M1 and M2. Assuming that no other forces are acting on them aside from gravity, what is the nature of their acceleration over time? As they approach each other, and their distance decreases, does their acceleration also increase? If so, what is the rate at which this...

    Angular tension on a hanging body

    I wasn't sure- every other time I've thought that I ended up being wrong. Thanks anyways- NJ

    Determine Acceleration from Position vs. Time Graph

    Your first assertion, that acceleration occurs only at curves is correct. Velocity is only equal to zero when it (the position function) has zero slope (ie, no motion--- straight lines and relative max/mins) and acceleration equals zero when the velocity is constant (velocity is a straight line)...

    Determine Acceleration from Position vs. Time Graph

    For a position as a function of time graph, simply find the derivative at the point which you wish to find the velocity for. Find the second derivative of the function for the acceleration. Perhaps if you uploaded an image of the particular graph in question I could be of more use. (The...

    Angular tension on a hanging body

    [SOLVED] Angular tension on a hanging body Homework Statement "In the diagram (see link), the tension on FT1 is 200N, angle measurements given are 50 deg and 30 deg left to right. What is the tension in FT2? What's the mass of the box?"...
