REMEMBER - Always write answers in complete sentences (Starting a sentence with "because" means it is probably incomplete.) - Be specific! (Avoid using the word "it" as much as possible). DIRECTIONS Using what you learned in about energy describe the energy transfer or transformations for each of the items below. 1. Clapping Your Hands: & 2. Dropping Your Pencil: 3. The Toaster: & 4. A Cat Lying in a Sunny Window: 5. Lifting a Book Over Your Head: & 6. The Radio: Now come up with two of your own examples and describe the energy transfer or transformation involved in each. 1. 2.

Answer 1

1. Clapping Your Hands: Chemical energy is transformed into kinetic energy, and some kinetic energy is transformed into sound energy. 2. Dropping Your Pencil: Gravitational potential energy is transformed into kinetic energy, and some kinetic energy is transformed into sound energy. 3. The Toaster: Electrical energy is transformed into thermal energy. 4. A Cat Lying in a Sunny Window: Light energy is transformed into heat energy. 5. Lifting a Book Over Your Head: Chemical energy is transformed into kinetic energy, and then kinetic energy is transformed into gravitational potential energy. 6. The Radio: Electrical energy is transformed into both sound energy and light energy.

Answer 2

The problem involves understanding the concept of energy transformation, which is a key concept in physics. Energy can be transferred from one form to another, and in this problem, you are asked to describe the energy transformation in various everyday situations. ## Step1: Clapping Your Hands: The energy transformation here starts with the chemical energy stored in your muscles. When you clap your hands, this chemical energy is converted into kinetic energy, which is the energy of movement. When your hands collide, some of this kinetic energy is transformed into sound energy, which is the clapping sound you hear. ## Step2: Dropping Your Pencil: The energy transformation begins with gravitational potential energy, which is the energy stored due to the raised object. When the pencil drops, this gravitational potential energy is converted into kinetic energy. Upon hitting the ground, some of this kinetic energy is transformed into sound energy. ## Step3: The Toaster: The toaster converts electrical energy into thermal energy, which is the heat used to toast your bread. ## Step4: A Cat Lying in a Sunny Window: The energy transformation here involves light energy from the sun being converted into heat energy, which is absorbed by the cat. ## Step5: Lifting a Book Over Your Head: This situation starts with chemical energy stored in your muscles, which is converted into kinetic energy to lift the book. This kinetic energy is then converted into gravitational potential energy, which is ready to be released if the book is dropped. ## Step6: The Radio: This situation involves multiple energy transformations. It converts electrical energy into both sound energy (the audio you hear) and light energy (for the backlight on the display).
