Energy

Energy is the capacity to do work and is a fundamental concept in physics. It exists in various forms, including kinetic (energy of motion), potential (energy stored in an object), thermal (heat energy), chemical (energy stored in chemical bonds), and more. Energy is essential for powering our daily lives and is conserved, meaning it cannot be created or destroyed but can change from one form to another. It plays a crucial role in virtually every aspect of our world, from powering vehicles to sustaining life on Earth.
