Front

Laminated Adjective

---

[lam-uh-nay-tid]

Back

Laminated

---

Constructed from multiple layers bonded together, such as plastic and glass, to hold the material together when it breaks.

---

Example: A cross-section of laminated glass shows layers bonded together for strength.

Front

Tempered Adjective

---

[tem-perd]

Back

Tempered

---

A type of safety glass strengthened by heating and rapid cooling, causing it to shatter into small, harmless pieces.

---

Example: Tempered glass is shown with stress distribution, explaining how it shatters safely.

Front

Shatterproof Adjective

---

[shat-er-proof]

Back

Shatterproof

---

Designed to resist breaking into sharp, dangerous splinters upon impact, often used for vehicle windows.

---

Example: Non-shatter rulers show how some materials are designed to resist breaking into dangerous pieces.

Front

Collision Noun

---

[kuh-lizh-uhn]

Back

Collision

---

An event in which two or more objects, such as vehicles, strike each other with significant force.

---

Example: Two spheres colliding, showing the impact and energy transfer.

Front

Air bag Noun

---

[air bag]

Back

Air bag

---

A safety device in a vehicle consisting of a fabric bag designed to inflate rapidly during a collision.

---

Example: The image shows an airbag inflating in a car during a collision, demonstrating its role in protecting passengers.

Front

Inflate Verb

---

[in-flayt]

Back

Inflate

---

To fill with air or gas, causing an object like an air bag to swell or expand quickly.

---

Example: An airbag inflates by filling with gas, causing it to expand and protect the driver.

Front

Deflate Verb

---

[dih-flayt]

Back

Deflate

---

To release air or gas from a filled object, causing it to empty and collapse after inflation.

---

Example: The image illustrates deflating a tire by pressing the valve to release air, causing the tire to collapse.

Front

Deploy Verb

---

[dih-ploy]

Back

Deploy

---

To activate or move into position for action, such as when an air bag opens automatically in a collision.

---

Example: An airbag deploying in a car during a collision shows how it moves into position for action.

Front

Crash-test dummy Noun

---

[krash-test duhm-ee]

Back

Crash-test dummy

---

A human-like model with sensors, used in controlled experiments to study the effects of forces in a collision.

---

Example: Crash-test dummies in a car show how they help study collision forces.

Front

Deceleration Noun

---

[dee-sel-uh-rey-shuhn]

Back

Deceleration

---

The rate at which a moving object slows down its speed, a key factor in vehicle safety design.

---

Example: A car stops, and a box on top continues moving forward, illustrating deceleration.
