FLASHCARD QUESTION
Front
Vector Noun
[vek-ter]
Back
Vector
A quantity that has both magnitude and direction, used to represent physical quantities like force or displacement.
Example: The arrow represents a vector, showing both the direction of the push (a force) and indicating it has a certain strength (magnitude).

FLASHCARD QUESTION
Front
Resultant Vector Noun
[ri-zuhl-tnt vek-ter]
Back
Resultant Vector
The single vector that is the sum of two or more vectors, representing their combined effect on an object.
Example: This image shows two forces (F1, F2) acting on a box being added together to create a single, combined force called the resultant vector (FR).

FLASHCARD QUESTION
Front
Magnitude Noun
[mag-ni-tood]
Back
Magnitude
The size, length, or amount of a vector, which is always a positive scalar quantity indicating 'how much'.
Example: A speedometer shows the magnitude of a car's speed, which is the amount or size of its speed, like 295 kilometers per hour.
4.
FLASHCARD QUESTION
Front
Direction Noun
[di-rek-shun]
Back
Direction
The orientation of a vector in space, typically defined by an angle measured from a reference axis.
Example: The arrows on the road and the traffic sign show that cars move in specific, opposite directions.

FLASHCARD QUESTION
Front
Displacement Noun
[dis-pleys-muhnt]
Back
Displacement
A vector quantity that refers to an object's overall change in position from its starting point to its end point.
Example: This icon shows an object moving down a ramp, representing a change in its position, which is the basic idea of displacement.

FLASHCARD QUESTION
Front
Components Noun
[kuhm-poh-nuhnts]
Back
Components
The projections of a single vector onto the perpendicular axes of a coordinate system, typically the x and y axes.
Example: A wave is made of several components, such as its highest point (crest), lowest point (trough), height (amplitude), and length.
7.
FLASHCARD QUESTION
Front
Vector Resolution Noun
[vek-ter rez-uh-loo-shun]
Back
Vector Resolution
The process of breaking down a single vector into its individual perpendicular components, such as its x-component and y-component.
Example: This diagram shows a force vector (purple arrow) being broken down, or resolved, into its separate vertical and horizontal parts (components).
