Types and Transformations of Energy

The video tutorial from the Lighthouse Lab explores various forms of energy, including sound, light, electricity, and heat. It delves into the concept of potential energy, explaining how it can exist due to an object's position, state, or composition. The tutorial provides examples of chemical potential energy, such as sparklers and batteries, and discusses gravitational potential energy using a toy roller coaster and bungee jumping. It also covers elastic potential energy with examples like a bow and arrow. The video emphasizes the transformation of potential energy into other energy forms.
