Answer:
Step-by-step explanation:
As you throw a book upward, two types of energy are given to the book:
Kinetic Energy: The book gains kinetic energy as it speeds up while you throw it upwards.
Potential Energy: The book gains potential energy as it moves upward against gravity.
The energy to throw the book comes from the food we eat, which provides the body with potential energy in the form of glucose. This glucose is broken down in the cells of our body, and the energy released is used to perform physical activities like throwing a book upwards.
The energy transformation involved in this process is the conversion of potential energy stored in the glucose molecule into kinetic energy of the body and ultimately into potential energy of the book. The energy transformation is an example of the Law of Conservation of Energy, which states that energy cannot be created or destroyed but can only be transformed from one form to another.
