Is Work Done by Different Forces Path-Dependent?

Click For Summary
SUMMARY

The discussion confirms that work done by conservative forces, such as gravity, is independent of the path taken, while work done by non-conservative forces, such as friction, is path-dependent. These principles are fundamental in classical mechanics and are essential for understanding energy conservation and dissipation in physical systems. The terminology used in this context is critical, as conservative forces are defined by their path independence, whereas non-conservative forces exhibit path dependence.

PREREQUISITES
  • Understanding of conservative and non-conservative forces
  • Basic principles of classical mechanics
  • Familiarity with work-energy theorem
  • Knowledge of energy conservation laws
NEXT STEPS
  • Study the work-energy theorem in detail
  • Explore examples of conservative and non-conservative forces
  • Learn about energy conservation in closed systems
  • Investigate the implications of path dependence in real-world applications
USEFUL FOR

Students of physics, educators teaching classical mechanics, and anyone interested in the principles of work and energy in physical systems.

can you help me check if these two statements are true?
1. work done by non-dissipative force is independent of the path that it takes ( ie: gravity)
2. work done by dissipative force is dependent of the path that it takes (ie: friction)

Huge thanks!

True. Although the convention is to call them conservative and non conservative forces.
