Name three types of energy transformations.
Energy is the ability to do work and can take many forms, such as mechanical, electrical, thermal, and chemical. Energy is transformed from one type to another when work is done. For example, when a car is driven, chemical energy in the fuel is converted to mechanical energy. The amount of energy is conserved, meaning it can never be created or destroyed, only changed from one form to another.
Energy Types & Transformations
Energy Transformation: A process in which energy is changed from one form to another, such as when electrical energy is converted to heat energy. Kinetic Energy: the energy of motion. It is the energy of an object that is caused by the object’s motion. Potential Energy: the stored energy of an object due to its position or condition. It is the energy an object has because of its location or arrangement.
The energy from the sun is used by plants in a process called photosynthesis to create a type of energy known as chemical energy. When you eat food, the chemical energy stored in the food is converted into a different type of energy called kinetic energy. Kinetic energy can be transformed into electrical energy through the use of a generator.
