    Force Field to Motion Equation

    Oh I hadn't thought about that but sure, it would be fine to assume that the initial velocity is zero. Yes we have discussed how to convert potential and force as well as how to convert acceleration or force to an equation of motion when it is given as a function of time. What is confusing me...

    Exercise: who does more work weight lifter/marathon runner

    When the weightlifter raises the bar, his muscles expend chemical energy, some of which is expended into the raising gravitation potential energy of the bar (the efficiency is not even close to perfect). When the bar is lowered, your muscles are unable to reabsorb the gravitational potential...

    Force Field to Motion Equation

    In my mechanics class, we have discussed basics dynamics relationships and equilibria aspects, and we recently considered Newton's Law of Gravitation. In our discussion, we went through how to determine potential energy and used this to perform most of our calculations with respect to velocity...

    Find the flux through the equilateral triangle with corners at

    Find the area vector of the triangle. Remember that it should be normal to the triangle's surface and have magnitude equal to the triangle's area.
