AP MECHANICS -C LEARNING OBJECTIVE CON 1.B -Derive an expression that represents the relationship between a conservative force acting in a system on an object to the potential energy of the system using the methods of calculus. 1.F -Derive an expression for the gravitational potential energy of a system consisting of a satellite or large mass (e.g., an asteroid) and the Earth at a great distance...
AP MECHANICS -C LEARNING OBJECTIVE CON 1.C -Describe the force within a system and the potential energy of a system. So far we have seen that a potential energy function U(x) can be found in the cases where conservative forces are acting in the system. We proved that in such cases the work done by the forces in a closed loop is always zero. For a one-dimensional case where the U varies only as a...
