The Rescue Team's Energy Needs

Front

Energy Noun

---

[en-er-jee]

Back

Energy

---

The ability to do work or cause change, which can be transferred or converted but never created or destroyed.

---

Example: A battery powers a light bulb, showing energy conversion from chemical to light energy.

Front

Kinetic Energy Noun

---

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

Back

Kinetic Energy

---

The form of energy that an object possesses because of its motion, dependent on its mass and speed.

---

Example: A cyclist speeds down a hill, gaining kinetic energy from motion.

Front

Potential Energy Noun

---

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

Back

Potential Energy

---

The stored energy an object has because of its position, condition, or the arrangement of its parts.

---

Example: A boulder on a hill has potential energy because of its elevated position.

Front

Transfer Verb

---

[trans-fur]

Back

Transfer

---

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

---

Example: Heat flows from a hot object to a cold object, transferring thermal energy.

Front

Convert Verb

---

[kun-vurt]

Back

Convert

---

To change energy from one form into a different form, such as changing potential energy into kinetic energy.

---

Example: A generator converts mechanical energy into electrical energy by rotating a coil within a magnetic field.

Front

System Noun

---

[sis-tum]

Back

System

---

A collection of interacting parts that form a complex whole where energy is transferred and converted within it.

---

Example: A solar system model shows how planets orbit the sun, illustrating a system of interacting parts.

Front

Generator Noun

---

[jen-uh-rey-ter]

Back

Generator

---

A machine specifically designed to convert mechanical energy, which is a form of kinetic energy, into electrical energy.

---

Example: The image shows how a generator uses magnetic fields and rotation to produce electricity.

Front

Fuel Noun

---

[fyool]

Back

Fuel

---

Any material that can be consumed, such as by burning, to release stored chemical energy as heat or work.

---

Example: Burning wood releases energy as heat, showing how fuel provides energy.

Front

Hydroelectric Power Noun

---

[hahy-droh-i-lek-trik pou-er]

Back

Hydroelectric Power

---

A type of renewable energy that is generated by converting the kinetic energy of moving water into electricity.

---

Example: Water flows from a reservoir through a turbine, generating electricity in a hydroelectric dam.

Front

Solar Power Noun

---

[soh-ler pou-er]

Back

Solar Power

---

Energy that is derived directly from the sun's radiation and converted into useful thermal or electrical energy.

---

Example: Solar radiation from the sun reaches Earth, demonstrating solar power.
