The faster those molecules or atoms collide, the more heat energy they emit.įor example, heat applied to a pot of water that causes the water to boil and produce heat energy, heat from the sun that increases the temperature of our atmosphere, and so on. What results from such a phenomenon is called thermal energy. When a substance or body is heated up (rise in temperature), its molecules and atoms begin to collide and vibrate faster with each other. Thermal energy: This can be called heat energy. It is this movement of electrons that leads to what we call electricity.įor example, a socket plugged into a wall power outlet could receive electricity and then convert the electrical energy into light energy.
Physics defines energy as the capacity of a body to do work while Biology defines energy as the ability to cause change. Definitions, Types, and Forms of EnergyĪ glimpse of this post: Energy exists in two types and various forms.
