There are three methods of energy transfer that we need to learn: conduction, convection, and radiation. 1. Conduction: Heat is thermal energy, and in solids it can be transferred by conduction. Heat is passed along from the hotter end of an object to the cold end by the particles in the solid vibrating. read more
There are obviously a lot of ways to do this; the chemical energy of a body or rocket, the electrical energy of an elevator, the thermal energy of a balloon. We call this potential energy. When the object is dropped, potential energy is changed to kinetic energy. read more
The transfer of heat by radiation involves the carrying of energy from an origin to the space surrounding it. The energy is carried by electromagnetic waves and does not involve the movement or the interaction of matter. read more
