Front

Molecule Noun

---

[mol-uh-kyool]

Back

Molecule

---

The smallest particle of a substance, made of one or more atoms, that is in constant, random motion.

---

Example: A water molecule is made of two hydrogen atoms and one oxygen atom bonded together.

Front

Kinetic Energy Noun

---

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

Back

Kinetic Energy

---

The energy that an object or particle possesses because it is in motion; all moving things have it.

---

Example: A Newton's cradle shows kinetic energy as moving balls transfer energy to each other.

Front

Collision Noun

---

[kuh-lizh-uhn]

Back

Collision

---

An instance where one moving particle or object strikes another, often resulting in a transfer of energy.

---

Example: Two objects collide, showing how energy transfers from one to the other.

Front

Temperature Noun

---

[tem-per-uh-cher]

Back

Temperature

---

A measure of the average kinetic energy of the molecules in a substance, indicating how hot or cold it is.

---

Example: Molecules in warmer areas move faster, showing higher temperature.

Front

Thermal Energy Noun

---

[thur-muhl en-er-jee]

Back

Thermal Energy

---

The total kinetic energy of all the molecules that make up a substance, dependent on temperature and quantity.

---

Example: Molecules in a hot area move faster, transferring thermal energy to a cooler area.

Front

System Noun

---

[sis-tuhm]

Back

System

---

A collection of interacting objects or parts that form a complex whole within which energy can be transferred.

---

Example: The model shows how planets orbit the sun, demonstrating the solar system as a complex whole.

Front

Transfer Noun

---

[trans-fur]

Back

Transfer

---

The movement of energy from one object or place to another, such as from a hotter to a colder object.

---

Example: Heat flows from the hot beaker to the cold beaker, showing energy transfer.

Front

Equilibrium Noun

---

[ee-kwuh-lib-ree-uhm]

Back

Equilibrium

---

The state where a system is balanced because energy is distributed evenly, resulting in a uniform temperature throughout.

---

Example: A balanced scale shows equilibrium, where forces are equal and stable.

Front

Stability Noun

---

[stuh-bil-i-tee]

Back

Stability

---

A state in which a system tends to remain unchanged because its properties, like total energy, are constant.

---

Example: Newton's cradle shows stability by conserving energy and maintaining motion.
