what is energy

Energy is the ability to do work or cause change. It is one of the most important things in the universe and is needed for everything that happens around us. Energy is found in many forms, including heat, light, sound, electrical, chemical, kinetic, and potential energy. We get energy from food, while plants get energy from sunlight. Energy helps us move, think, play, and keeps our bodies working. It also powers homes, schools, factories, vehicles, and electronic devices. Energy can change from one form to another, such as electrical energy changing into light and heat in a bulb, or chemical energy in food changing into movement when we run. According to the law of conservation of energy, energy cannot be created or destroyed—it can only be transferred or transformed. Without energy, nothing could move, grow, or function. ⚡
