FLASHCARD QUESTION

Front

Position-Time Graph Noun

[puh-zish-un tahym graf]

Back

Position-Time Graph


A graph representing an object's motion by plotting position on the vertical axis and time on the horizontal axis.

Example: This graph shows an object's position changing over time. The straight, upward-sloping line indicates the object is moving at a constant, positive speed.

FLASHCARD QUESTION

Front

Motion Diagram Noun

[moh-shun dahy-uh-gram]

Back

Motion Diagram


A simplified representation showing an object's position at various, often equally spaced, moments in time.

Example: This diagram shows an object's position at equal time intervals (0, 1, 2...). The increasing space between dots indicates the object is accelerating.

FLASHCARD QUESTION

Front

Position Noun

[puh-zish-un]

Back

Position


The specific location of an object relative to a defined origin or reference point in a coordinate system.

Example: This image shows that position is a specific location on a reference frame, like a number line. To plot a position-time graph, you must first locate the position value on an axis.

FLASHCARD QUESTION

Front

Origin Noun

[or-i-jin]

Back

Origin


A fixed reference point, designated as zero, from which all positions are measured in a coordinate system.

Example: This graph shows the origin, which is the starting point where the x-axis and y-axis intersect, at the coordinates (0, 0).

FLASHCARD QUESTION

Front

Best-fit line Noun

[best fit lahyn]

Back

Best-fit line


A straight line drawn on a graph that best represents the general trend of a set of data points.

Example: This graph shows scattered data points and a straight line of best fit that represents the general trend, showing how an object's velocity changes over time.

FLASHCARD QUESTION

Front

Instantaneous position Noun

[in-stun-tey-nee-uhs puh-zish-un]

Back

Instantaneous position


The position of an object at a single, specific moment or instant in time, represented by a point.

Example: This graph shows an object's position over time. The point p1 represents the object's exact location (its instantaneous position) at a specific moment in time.

FLASHCARD QUESTION

Front

Displacement Noun

[dis-pleys-muhnt]

Back

Displacement


The change in an object's position from its starting point to its ending point, including both magnitude and direction.

Example: A person moves from an initial position (x₀) to a final position (x_f), and the displacement (Δx) is the direct change in position from start to finish.
