What I Have Learned Directions: Answer the following questions in paragraph form. Write your answers in your answer sheet. 1. What is energy? 2. What are the types of energy? 3. What are the forms of energy? 4. Describe sound, heat, light, and electrical energy? 5. Give one example of each form of energy.

2.The different types of energy include thermal energy, radiant energy, chemical energy, nuclear energy, electrical energy, motion energy, sound energy, elastic energy and gravitational energy.

3.Energy exists in many different forms. Examples of these are: light energy, heat energy, mechanical energy, gravitational energy ,electrical energy, sound energy, chemical energy, nuclear or atomic energy and so on. Each form can be converted or changed into the other forms.

4.Heat, light, and sound are all forms of energy. Heat can be transferred by radiation, conduction and con- vection. Visible light can be produced, reflected, refracted, and separated into light of various colors. Sound is created by vibration and cannot travel through a vacuum.

5.Energy exists in many different forms. Examples of these are: light energy, heat energy, mechanical energy, gravitational energy, electrical energy, sound energy, chemical energy, nuclear or atomic energy and so on. Each form can be converted or changed into the other forms.

REGUELYNIN REGUELYNIN · Answer 2

Answer:

1.must be transferred to a body or physical system to perform work on the body, or to heat it. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed.

2.Many forms of energy exist, but they all fall into two basic categories: Potential energy. Kinetic energy.

3Energy exists in many different forms. Examples of these are: light energy, heat energy, mechanical energy, gravitational energy, electrical energy, sound energy, chemical energy, nuclear or atomic energy and so on. Each form can be converted or changed into the other forms.
