Aug 27, 2024 · Uses of Light Energy 1. Photosynthesis. Photosynthesis is a process used by plants, algae, and some bacteria to convert light energy into chemical energy. This process is essential for the production of oxygen and glucose, which are vital for the survival of most life forms on Earth. 2. Vision. Light energy enables vision in humans and animals.
- Kinetic Energy. Any moving things use kinetic energy. For example, flying an airplane in the sky, throwing balls, running, cycling, climbing, etc are examples of kinetic energy.
- Chemical Energy. Chemical energy is the energy that is stored in the bonds of atoms and molecules. When this chemical reaction occurs, this energy is released.
- Electrical Energy. Electrical energy is moving energy that is generated by tiny charged particles called electrons and protons. A lightning bolt is one form of electrical energy.
- Heat Energy. Heat energy is also known as Thermal Energy. The energy that comes from a fire is thermal energy. As we know matter is made up of molecules.
