Designing an Energy Solution

Front

Kinetic Energy Noun

---

[ki-net-ik en-er-jee]

Back

Kinetic Energy

---

The energy an object possesses due to its motion, which is proportional to its mass and speed.

---

Example: A cyclist going downhill gains kinetic energy as they speed up due to gravity.

Front

Potential Energy Noun

---

[po-ten-shuhl en-er-jee]

Back

Potential Energy

---

Stored energy a system of objects has based on their relative positions or internal chemical state.

---

Example: A boulder at the top of a hill has potential energy due to its position.

Front

Electrical Energy Noun

---

[ih-lek-tri-kuhl en-er-jee]

Back

Electrical Energy

---

A form of energy that results from the movement or flow of electric charge through a material.

---

Example: A battery powers a light bulb through a closed circuit, demonstrating electrical energy flow.

Front

Convert Verb

---

[kuhn-vurt]

Back

Convert

---

To change energy from one form into another, such as changing motion into electrical energy.

---

Example: A battery converts chemical energy into electrical energy to light a bulb.

Front

Transfer Verb

---

[trans-fur]

Back

Transfer

---

To move energy from one object or location to another without changing its fundamental form.

---

Example: A ball in motion transfers energy to the next ball in a Newton's cradle, demonstrating energy transfer.

Front

Conservation of Energy Noun

---

[kon-ser-vey-shuhn uhv en-er-jee]

Back

Conservation of Energy

---

The scientific principle stating that energy cannot be created or destroyed, only converted or transferred.

---

Example: A swinging ball transfers energy to the next, showing energy conservation.

Front

Energy System Noun

---

[en-er-jee sis-tuhm]

Back

Energy System

---

A set of connected parts that work together to transfer and convert energy for a specific purpose.

---

Example: A battery powers a light bulb through a circuit, showing energy transfer and conversion.

Front

Generator Noun

---

[jen-uh-rey-ter]

Back

Generator

---

A device specifically designed to convert the energy of motion, or mechanical energy, into electrical energy.

---

Example: The image shows how a generator uses magnetic poles and a rotating coil to produce electricity.

Front

Model Noun

---

[mod-l]

Back

Model

---

A representation of an object or system used to help understand and explain how something works.

---

Example: A model of the solar system shows how planets orbit the sun.

Front

Criteria Noun

---

[krahy-teer-ee-uh]

Back

Criteria

---

The specific goals, requirements, and standards that a design must meet to be considered successful.

---

Example: A checklist represents criteria as goals or standards to meet in a design.
