Energy Transfers and Transformations in Different Systems

The video tutorial explains energy transfer and conservation through various examples. It covers how energy changes form and is transferred in different scenarios, such as a ball being projected, a Newton's cradle, braking in a vehicle, boiling water in an electric kettle and on a stove, and a battery-powered torch. The overarching theme is that energy is conserved, meaning it cannot be created or destroyed, only transformed.

What type of energy transfer occurs when water is boiled in an electric kettle?

How is chemical energy converted when a battery-powered torch is switched on?
