Is It Possible for a System to Have Negative Potential

question 51

Multiple Choice

Is it possible for a system to have negative potential energy?

• A) Yes, as long as the kinetic energy is positive.
• B) Yes, as long as the total energy is positive.
• C) Yes, since the choice of the zero of potential energy is arbitrary.
• D) No, because the kinetic energy of a system must equal its potential energy.
• E) No, because this would have no physical meaning.

Definitions:

Concurrent Validity

Concurrent validity is the extent to which test scores or measurements are correlated with other measures or outcomes that are theoretically related and taken at the same time.

Predictive Validity

How well a result from a test or scale forecasts subsequent performance in a connected area.

Face Validity

The degree to which a test or measure appears effectively to assess what it is supposed to assess, based on casual inspection.

Content Validity

An indicator of construct validity of a measure in which the content of the measure is compared to the universe of content that defines the construct.
