a) The work done by a nonconservative force depends on the path taken. True.

c) A potential energy function can be specified for a conservative force. True

d) A conservative force permits a two-way conversion between kinetic and potential energies. True

Explanation:

Non-conservative forces dissipate. For example, friction or air resistance or drag.

A conservative force's property is that the work done in moving a particle does not depend on the path it has taken. For example, stored energy or potential energy. It permits two-way conversion between kinetic energy and potential energy. For example if a car goes up a hill, it converted kinetic energy in to potential energy. and if the car goes down the hill without hitting the gas pedal, it will roll down converting the potential energy in to kinetic energy.

b) A nonconservative force permits a two-way conversion between kinetic and potential energies. False

e) A potential energy function can be specified for a nonconservative force. False

f) The work done by a conservative force depends on the path taken. False
