  1. Conservation of Energy: The principle that states energy cannot be created nor destroyed, only transferred or transformed. "

  2. Work, energy, and power are fundamental concepts in physics that describe how objects interact and change. These principles explain how forces cause motion, how energy is transferred and transformed, and how quickly work is done in various systems.

  3. Energy in modern physics refers to the concept of energy as understood through the principles of quantum mechanics and relativity. It involves understanding how energy is quantized and how it relates to mass, momentum, and other fundamental quantities.

  4. • Potential energy is energy in the future (energy that is available for use). • Kinetic energy is energy in the present (the energy of an object that is currently in motion). • Work is the result of energy in the past (the result of potential or kinetic energy having acted on an object).
