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