Practice question · Sort into groups
Sort these forces into Conservative or Non-conservative.
Groups: Conservative · Non-conservative
- Tension (with deformation)
- Electrostatic force
- Air resistance
- Spring force
- Gravity
- Kinetic friction
Hints
- Ask whether the work done depends on the route taken.
- Anything that dissipates energy as heat fails the test.
Show the answer
Conservative: Gravity, Spring force, Electrostatic force
Non-conservative: Kinetic friction, Air resistance, Tension (with deformation)
Why
Conservative forces have path-independent work; friction and drag do not.
