Understanding Matter and Energy Concepts

Michael C. Corpus discusses the interactions of energy and matter. Energy is defined as the ability to perform work and is essential for any activity. Various examples illustrate the necessity of energy, such as talking, working, and driving a car. Energy exists in different forms, including potential and kinetic energy. Matter is defined as anything that occupies space and has mass, with examples like a cup or a car. Matter exists in three physical states: solid, liquid, and gas, and is composed of atoms.
