Question

Which of the following statements is/are true? Check all that apply. Check all that apply. The work done by a conservative force depends on the path taken. A potential energy function can be specified for a conservative force. A potential energy function can be specified for a nonconservative force. A conservative force permits a two-way conversion between kinetic and potential energies. A nonconservative force permits a two-way conversion between kinetic and potential energies. The work done by a nonconservative force depends on the path taken.

Answer 1

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

FALSE

Conservative field work done is always independent of path but it only depends on initial and final position

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

TRUE

Potential energy is defined as negative work done by the conservative field force.

3). A potential energy function can be specified for a non-conservative force.

FALSE

Potential energy is defined only for the conservative field work

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

TRUE

In case of conservative field mechanical energy is always conserved.

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

FALSE

When non-conservative force is present then energy is lost due to these type of forces.

6). The work done by a non-conservative force depends on the path taken.

TRUE

non-conservative field force is always based upon the path along which object is displaced
