Question

Which of the following statements is true regarding the potential energy of a system?

• A. The potential energy of a system can convert into kinetic energy.
• B. The potential energy of a system always remains negative.
• C. The potential energy of a body depends on its speed.
• D. The potential energy of a system always remains positive.

Answer 1

The correct option is A The potential energy of a system can convert into kinetic energy.

When the mechanical energy of a system is conserved, the kinetic and potential energies may convert into each other.

$Kineticenergy+Potentialenergy=Mechanicalenergy$
