What is an energy transfer?

Energy transfer is the process of moving energy from one system to another. It occurs in various forms such as heat, light, sound, and electromagnetic waves. Energy can be transferred by conduction, convection, and radiation. Conduction is the transfer of heat between two objects that are in direct contact, while convection occurs when heat is transferred through a fluid or gas. Radiation is the transfer of energy through electromagnetic waves, which travel through space. One of the most common forms of energy transfer is the conversion of potential energy to kinetic energy, such as when a ball is thrown upwards and returns to the ground. Another example is when solar energy is converted into electricity through the use of solar panels. Energy transfer is a fundamental concept in physics and is present in all aspects of our daily lives.
