### Energy Terms in Pendulum Motion #### Diagram Description: The diagram depicts a simple pendulum in three different positions: 0, 1, and 2. The pendulum bob is shown hanging from a pivot point at the top, swinging to the left (position 2) and right (position 0) and as well as at the equilibrium position (position 1). The dotted lines represent the path of the pendulum as it swings back and forth. The gravitational potential energy at the equilibrium position (point 1) is marked as \( U_G = 0J \). #### Questions: 1. **At the point labeled “0” in the figure, which of the following energy terms are nonzero? Select all that apply.** - A) \( U_G \) - B) \( U_S \) - C) \( K_T \) - D) these are all zero 2. **At the point labeled “1” in the figure, which of the following energy terms are nonzero? Select all that apply.** - A) \( U_G \) - B) \( U_S \) - C) \( K_T \) - D) these are all zero #### Explanation: - **\( U_G \)**: Gravitational potential energy. - **\( U_S \)**: Spring potential energy (Note: This is not typically applicable in simple pendulum problems unless there is a spring involved, which is unusual). - **\( K_T \)**: Kinetic energy. #### Analysis of Pendulum Positions: - At the point labeled "0" (maximum displacement to the right), the pendulum has maximum gravitational potential energy due to its height and zero kinetic energy if it comes momentarily to rest. - At the point labeled "1" (equilibrium position), the gravitational potential energy is zero by definition, and the kinetic energy is maximal if there is no damping. - At the point labeled "2" (maximum displacement to the left), similar to point "0", the pendulum has maximum gravitational potential energy and zero kinetic energy if it is momentarily at rest. These aspects should be considered while selecting the appropriate answers for the questions provided.
