Question

The "mechanical energy" of a system is the sum of its kinetic and potential energies. When a non-conservative force does work on a system, what happens to that system's mechanical energy? Choice 1 of 3: The mechanical energy increases. Choice 2 of 3: The mechanical energy decreases. Choice 3 of 3: The mechanical energy stays constant.

Step 1

Mechanical energy is the sum of a system's kinetic energy (energy of motion) and potential energy (energy stored due to position or shape). It is a measure of the total energy that a system possesses due to its motion and configuration. Show more…
