Forms of Energy and Their Applications

Jacob and Sam from Science for Kids explore various forms of energy, including sound, heat, light, electricity, nuclear, chemical, gravitational, and elastic potential energy. They demonstrate how each type of energy can cause change, using practical examples like tuning forks, gas stoves, magnesium ribbons, and more. The video aims to educate children on the different forms of energy and their applications.
