 Energy is the ability to do work or produce change. It comes in various forms such as kinetic energy (energy of motion), potential energy (stored energy), thermal energy (heat), chemical energy (energy stored in chemical bonds), and many others. According to the law of conservation of energy, energy cannot be created or destroyed, only transferred or converted from one form to another. This means that the total energy of a closed system remains constant over time. Energy is fundamental to all processes in the universe and plays a crucial role in every aspect of our lives.

 In physics, work is defined as the product of force and displacement in the direction of the force. Mathematically, it's represented as: W=Fd Where: - \( W \) = Work done - \( F \) = Force applied - \( d \) = Displacement - \( \theta \) = Angle between the force vector and the displacement vector
