Objective: Determine the conditions under which mechanical energy is stored in a pendulum. Instructions: In this forum, comment on the following case: The pendulum with a wooden mass [Consider a situation in which a pendulum made of a wooden sphere. The mass of the pendulum is 100 g of dough and the length of 1 m. If it is hung on the ceiling of a room, it is oscillated. What causes the mechanical energy of the pendulum to be conserved, if this energy is conserved?] Make your arguments based on physics and comment on the positions of at least two of your classmates, making sure that your comments to your classmates are not a simple "I agree" or "I disagree." That is, validate or invalidate the argument(s) of your classmates
