MS-ETS1-4: Engineering Design Optimization

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 its speed and mass.

---

Example: A cyclist gains kinetic energy as they speed downhill.

Front

Collision Noun

---

[kuh-lizh-uhn]

Back

Collision

---

An event where two or more bodies exert strong forces on each other in a relatively short time.

---

Example: Two balls colliding with arrows showing the direction of force.

Front

Mass Noun

---

[mas]

Back

Mass

---

A measure of the amount of matter in an object, affecting the energy transferred during a collision.

---

Example: A balance scale with a feather and a rock shows how mass affects balance.

Front

Force Noun

---

[fors]

Back

Force

---

A push or pull on an object that can cause it to change its motion, speed, or direction.

---

Example: A person pushing a box shows how force can move an object.

Front

Impulse Noun

---

[im-puls]

Back

Impulse

---

A change in momentum, resulting from a force being applied to an object over a period of time.

---

Example: A spring pushes a ball, changing its momentum over time.

Front

Crumple Zones Noun

---

[krum-puhl zohns]

Back

Crumple Zones

---

Areas of a vehicle designed to deform and absorb energy during a collision to protect the occupants.

---

Example: Crash test dummies in a car show how crumple zones protect passengers in a collision.

Front

Tempered Safety Glass Noun

---

[tem-perd seyf-tee glas]

Back

Tempered Safety Glass

---

A type of glass treated for strength that shatters into small, blunt pieces instead of sharp shards.

---

Example: The image shows how tempered glass is under tension and compression, explaining its strength and safe shattering.

Front

Laminated Windshields Noun

---

[lam-i-ney-tid wind-sheelds]

Back

Laminated Windshields

---

Windshields made with a layer of plastic between two layers of glass to prevent shattering upon impact.

---

Example: The image shows a laminated windshield with plastic between glass layers to prevent shattering.

Front

Air Bag Noun

---

[air bag]

Back

Air Bag

---

A safety device that rapidly inflates during a collision to cushion occupants from impact with the vehicle's interior.

---

Example: The image shows an airbag inflating to protect a driver during a collision.

Front

Deceleration Noun

---

[dee-sel-uh-rey-shuhn]

Back

Deceleration

---

The rate at which an object slows down; a negative acceleration that reduces an object's velocity over time.

---

Example: A car stops suddenly, and a box on top slides forward, showing deceleration.
