📚 Topic Summary
Energy is the ability to do work. It exists in different forms, such as kinetic (motion), potential (stored), thermal (heat), electrical, light (radiant), and chemical energy. Energy transformations occur when energy changes from one form to another. For example, a light bulb transforms electrical energy into light and heat energy. Understanding these forms and transformations is key to understanding how the world around us works!
🧪 Part A: Vocabulary
Match the term with its definition:
| Term |
Definition |
| 1. Kinetic Energy |
A. Stored energy due to position or condition. |
| 2. Potential Energy |
B. Energy of electromagnetic waves. |
| 3. Thermal Energy |
C. Energy of motion. |
| 4. Radiant Energy |
D. Energy of moving electrons. |
| 5. Electrical Energy |
E. Energy associated with the random motion of atoms and molecules. |
Match the correct letter to the number.
✍️ Part B: Fill in the Blanks
Fill in the blanks with the correct word from the box: Chemical, Kinetic, Potential, Thermal, Transformation
Energy __________ is the process of energy changing from one form to another. For example, when you eat food, your body converts the __________ energy in the food into __________ energy that allows you to move. A rollercoaster at the top of a hill has a lot of __________ energy. When brakes are applied to a car, __________ energy is also produced.
🤔 Part C: Critical Thinking
Describe a real-world scenario (other than the examples already given) where multiple energy transformations occur. Explain each step of the transformation.
