Questions and Answers

In a conservative mechanical system, which of the following statements about potential energy is true?

  • It is only dependent on the object's speed.
  • It is associated with conservative forces and does not depend on the path taken. (correct)
  • It is unrelated to the type of force acting on the system.
  • It is associated with dissipative forces and varies based on the path taken.

    • What is the relationship between potential energy functions and conservative forces in a system?

  • Conservative forces are not affected by potential energy functions.
  • Potential energy functions are solely determined by the object's mass.
  • The potential energy functions are related to conservative forces and can be used to determine the relationships between the two physical quantities. (correct)
  • There is no direct relationship between potential energy functions and conservative forces.

    • What type of force is associated with the potential energy function of an ideal spring?
