Question
As you lift a book into the air, what kind of energy are you increasing in the book?A.Elastic energyB.Nuclear energyC.Thermal energyD.Gravitational potential energy
Solution
As you lift a book into the air, you are increasing its Gravitational potential energy. So, the answer is D. Gravitational potential energy.
Here's why:
Step 1: Understand the question. The question is asking what type of energy is increased when you lift a book into the air.
Step 2: Understand the types of energy.
- Elastic energy is stored in objects by the application of a force (Compression, bending, stretching, etc.)
- Nuclear energy is the energy in the nucleus, or core, of an atom.
- Thermal energy is the internal energy of an object due to the kinetic energy of its atoms and/or molecules.
- Gravitational potential energy is energy an object possesses because of its position in a gravitational field.
Step 3: Apply the knowledge. When you lift a book, you're moving it against the force of gravity. This increases its position in the gravitational field, thus increasing its gravitational potential energy.
