What exactly is energy and why is it so important in physics? In this video, we will learn the concept of energy in physics. We will analyze the ability of energy to perform work and analyze how many forms of energy exist in the universe. Why can energy only be converted back and forth between different forms and cannot be properly destroyed or created? That is the law of conservation of energy, a core concept in physics. And the last interesting thing is that the nature of mass is also a form of energy.
