The document discusses different types of energy: potential energy is stored energy while kinetic energy is energy in motion. Energy can change forms, such as kinetic energy changing to potential energy. The law of conservation of energy states that energy cannot be created or destroyed, only transferred or changed from one form to another. The first law of thermodynamics states that the total energy of an isolated system remains constant. An object gains energy when work is done on it, such as applying a force to set it in motion. Energy can transfer between objects or systems through different processes like conduction, convection and radiation.
2. Energy and Work are the same. -Energy is the ability to do work - Work is a force applied to an object (a push or pull)
3. Potential and Kinetic Energy are different. -Potential Energy is stored energy. - Kinetic Energy is energy in motion.
4. Can energy change from one form to another? -Kinetic- energy in motion -Potential- stored energy -Radiant- energy in the form of electromagnetic waves
