Force and Motion Force, Motion, and Movie Sets

Front

Cause Noun

---

[kawz]

Back

Cause

---

An event, condition, or action that directly makes something else, known as an effect, happen in a predictable way.

---

Example: Pushing a box causes it to move, demonstrating force as a cause of motion.

Front

Effect Noun

---

[ih-fekt]

Back

Effect

---

A result or consequence that is the direct outcome of a preceding action or cause in a system.

---

Example: A ball rolling down a slope due to gravity shows the effect of force on motion.

Front

Force Noun

---

[fors]

Back

Force

---

A push or a pull on an object that can cause a change in its motion, having both strength and direction.

---

Example: A ball rolling down a slope shows force causing motion.

Front

Mass Noun

---

[mas]

Back

Mass

---

The measure of the amount of matter contained within a physical object, which determines its resistance to changing motion.

---

Example: A balance scale with a feather and a rock shows that mass is the amount of matter in an object.

Front

Velocity Noun

---

[vuh-los-i-tee]

Back

Velocity

---

The rate at which an object changes its position in a specific direction, combining both its speed and direction.

---

Example: A ball is pushed by a spring, showing velocity as it moves in a specific direction.

Front

Speed Noun

---

[speed]

Back

Speed

---

The rate at which an object covers distance over a period of time, without regard to its direction of motion.

---

Example: A car travels a certain distance over time, illustrating speed as distance divided by time.

Front

Sum of the Forces Noun

---

[suhm uv thuh for-sez]

Back

Sum of the Forces

---

The total, or net, force acting on an object, which is calculated by combining all individual forces together.

---

Example: A person pushing a box shows the direction of net force acting on an object.

Front

Friction Noun

---

[frik-shuhn]

Back

Friction

---

A force that opposes motion when two surfaces are in contact, acting in the direction opposite to the movement.

---

Example: A box on a surface with arrows showing friction opposing the applied force.

Front

Collision Noun

---

[kuh-lizh-uhn]

Back

Collision

---

An event where two or more objects exert powerful forces on each other over a very short time interval.

---

Example: Two objects moving towards each other collide, exerting forces and changing motion.

Front

Kinetic Energy Noun

---

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

Back

Kinetic Energy

---

The energy an object possesses because of its motion, which is dependent on both its mass and its speed.

---

Example: A cyclist moving down a hill gains kinetic energy due to increased speed.
