Questions and Answers

What is a system in the context of the chapter?

  • A region of space with varying boundaries
  • A collection of objects or particles with no specific boundaries
  • A single object or particle
  • A small portion of the Universe with defined boundaries (correct)

What is one of the three ways to store energy in a system?

  • Kinetic energy
  • Thermal energy
  • Potential energy (correct)
  • Electromagnetic energy

Why is the concept of energy considered one of the most important topics in science and engineering?
