Questions
  1. Statement is true
    Yes
    Statement
    A conservative force does path-independent work.
  2. Statement is true
    Yes
    Statement
    Its work depends only on the end points.
  3. Statement is true
    Yes
    Statement
    Its work around any closed path is zero.
  4. Statement is true
    No
    Statement
    A conservative force does more work on a longer route.
  5. Statement is true
    Yes
    Statement
    A potential energy function can be defined for a conservative force.
A force is conservative if its work is path-independent, or equivalently zero round any closed path. Source: syllabus Physics, Ch 5 Work, Energy and Power.
