Collision Engineering

Front

Kinetic Energy Noun

---

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

Back

Kinetic Energy

---

The energy an object possesses due to its motion, which increases with the object's speed and mass.

---

Example: A cyclist speeds down a hill, gaining kinetic energy as they move faster.

Front

Mass Noun

---

[mas]

Back

Mass

---

The amount of matter in an object, which helps determine the energy transferred during a collision.

---

Example: A Newton's cradle shows how mass affects energy transfer in collisions.

Front

Impulse Noun

---

[im-puls]

Back

Impulse

---

A physical quantity representing a force applied to an object over a specific period of time.

---

Example: A spring pushes a ball, showing force applied over time, illustrating impulse.

Front

Deceleration Noun

---

[dee-sel-uh-rey-shuhn]

Back

Deceleration

---

The rate at which an object slows down or decreases its velocity, a key factor in vehicle safety design.

---

Example: A car stopping suddenly causes a box on top to move forward, illustrating deceleration and inertia.

Front

Collision Noun

---

[kuh-lizh-uhn]

Back

Collision

---

An event where two or more objects forcefully impact each other, resulting in an exchange of energy and momentum.

---

Example: Two balls colliding with arrows showing the direction of impact, illustrating energy and momentum exchange.

Front

Crumple Zone Noun

---

[kruhm-puhl zohn]

Back

Crumple Zone

---

A structural area of a vehicle designed to absorb impact energy by deforming in a controlled way during a collision.

---

Example: The image shows a car's crumple zones, which absorb energy in a crash to protect passengers.

Front

Safety Compartment Noun

---

[seyf-tee kuhm-part-muhnt]

Back

Safety Compartment

---

The reinforced passenger area of a vehicle, engineered to resist deformation and protect occupants during a collision.

---

Example: The image shows a car's safety compartment with crash test dummies, demonstrating how it protects passengers in a crash.

Front

Tempered Glass Noun

---

[tem-perd glas]

Back

Tempered Glass

---

A type of safety glass that shatters into small, blunt pieces instead of sharp shards when broken.

---

Example: Illustrates how tempered glass is under tension and compression, showing its shatter pattern.

Front

Laminated Glass Noun

---

[lam-i-ney-tid glas]

Back

Laminated Glass

---

Safety glass with a plastic inner layer that holds the glass together when shattered, commonly used for vehicle windshields.

---

Example: Laminated glass has two glass layers with a plastic layer in between for safety.

Front

Air Bag Noun

---

[air bag]

Back

Air Bag

---

A vehicle safety device that rapidly inflates during a collision to cushion occupants and increase their stopping time.

---

Example: An airbag inflates to cushion the driver during a collision, increasing stopping time and reducing injury.
