Question

Learning Goal Part G To be able to interpret potential energy diagrams and predict the corresponding motion of a particle Name all labeled points on the graph corresponding to unstable equilibrium Potential energy diagrams for a particle are useful in predicting the motion of that particle. These diagrams allow one to determine the direction of the force acting on the particle at any point, the points of stable and unstable equilibrium, the particle's kinetic energy, etc. Consider the potential energy diagram shown. (Figure 1) The curve represents the value of potential energy U as a function of the particle's coordinate r The horizontal line above the curve represents the constant value of the total energy of the particle E The total energy E is the sum of kinetic (K) and potential (U) energies of the particle List your choices alphabetically, with no commas or spaces; for instance, if you choose points B, D, and E, type your answer as BDE View Available Hint(s) Submit Part H This question will be shown after you complete previous question(S) The key idea in interpreting the graph can be expressed in the equation Part I This question will be shown after you complete previous question (s) Flzd) gure 1 of 1 Part J Name all labeled points such that when a particle is released from rest there, it would accelerate to the left. List your choices alphabetically, with no commas or spaces; for instance, if you choose points B, D, and E, type your answer as BDE View Available Hint(s) Submit A BCD F G H
