Homework Help: physics to be conceptualize

Posted by member of physics on Tuesday, October 23, 2012 at 12:37am.

Which of the following statements are FALSE? Select all that apply.
In an isolated system where only conservative forces cause energy changes, the kinetic energy and potential energy of the system can change, but the mechanical energy of the system cannot change.
When the mechanical energy of a system is conserved, we can relate the sum of kinetic energy and potential energy at one instant to that at another instant without finding the work done by the forces involved.
The work done by a conservative force on a particle moving between two points must depend on the path taken by the particle.
