MS-PS2-1: Newton's Third Law

Front

Force Noun

---

[forss]

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 force as a push that can move objects.

Front

Motion Noun

---

[moh-shun]

Back

Motion

---

The action or process of an object changing its physical position over a period of time.

---

Example: A Newton's cradle demonstrates motion as balls transfer energy and change position over time.

Front

Acceleration Noun

---

[ak-sel-uh-rey-shun]

Back

Acceleration

---

The rate at which an object's velocity changes over time, which is proportional to force and inversely proportional to mass.

---

Example: The image shows how force, mass, and acceleration are related in the equation F=ma.

Front

Mass Noun

---

[mas]

Back

Mass

---

The measure of the amount of matter in an object, which determines its resistance to a change in motion.

---

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

Front

Friction Noun

---

[frik-shun]

Back

Friction

---

A force that resists and opposes the relative motion between two surfaces that are in contact with each other.

---

Example: A box on a surface shows friction as a force opposing motion, with a close-up of the contact area.

Front

Gravity Noun

---

[grav-i-tee]

Back

Gravity

---

The natural force that attracts any two objects with mass toward each other, like pulling things toward Earth's center.

---

Example: Arrows show gravity pulling objects toward each other, like Earth pulling objects toward its center.

Front

Air Resistance Noun

---

[air ree-zis-tuhns]

Back

Air Resistance

---

A type of frictional force that acts on objects as they move through the air, slowing them down.

---

Example: A parachute slows descent due to air resistance opposing gravity.

Front

Radiant Energy Noun

---

[rey-dee-uhnt en-er-jee]

Back

Radiant Energy

---

Energy that travels in waves or particles, such as electromagnetic radiation like light, heat, and radio waves.

---

Example: Arrows show radiant energy from the Sun traveling to Earth, illustrating energy transfer in waves.

Front

Theory of Special Relativity Noun

---

[thee-uh-ree uv spesh-uhl rel-uh-tiv-i-tee]

Back

Theory of Special Relativity

---

A scientific theory by Albert Einstein that explains the fundamental relationship between space and time for moving objects.

---

Example: The image shows how time passes differently on Earth and in a moving spaceship, illustrating time dilation.

Front

Traumatic Brain Injury (TBI) Noun

---

[traw-mat-ik breyn in-juh-ree]

Back

Traumatic Brain Injury (TBI)

---

A type of injury that disrupts normal brain function, typically caused by a sudden blow or jolt to the head.

---

Example: A blow to the head causes the brain to move, leading to a concussion, a type of TBI.
