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

A nonconservative force permits a two-way conversion between kinetic and potential energies. TRUE

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

FALSE

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

FALSE

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

FALSE

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

TRUE

Explanation:

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

This kind of force can not be obtained from potential function so the work made by this kind of force depend of the path taken.

A nonconservative force permits a two-way conversion between kinetic and potential energies. TRUE

A nonconservative force permits conversion to kinetic energy plus potential energy during it made work over the system.

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

FALSE

Considering that the work made by kind of force depend of the taken path they can not be determined by a potential fuction.

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

FALSE

This asseveration is related with the previous one. So the conservative force can be deducted from a potential function thus their y work made do not depend of the path taken.

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

FALSE

This means that as conservative force is related from a potential function it only can modify the potential energy of the system.

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

TRUE

This is as consequence of the definition of conservative force that it can be determined from a potential function.
