FLASHCARD QUESTION
Front
Acceleration Noun
[ak-sel-uh-rey-shuhn]
Back
Acceleration
The rate at which an object's velocity changes over time, which can involve a change in speed or direction.
Example: This formula triangle shows how to calculate acceleration (a) by dividing velocity (v) by time (t), a key mathematical relationship for motion.

FLASHCARD QUESTION
Front
Velocity Noun
[vuh-los-i-tee]
Back
Velocity
A vector quantity that specifies the rate of change of an object's position, indicating both its speed and direction.
Example: This diagram shows the formula triangle for velocity (v), which is calculated by dividing displacement (d) by time (t).

FLASHCARD QUESTION
Front
Position Noun
[puh-zish-uhn]
Back
Position
The specific location of an object in space, usually defined relative to a fixed reference point or origin.
Example: This diagram shows an object's position as its specific location (like -2 or 5) on a number line, which acts as a coordinate system.

FLASHCARD QUESTION
Front
Displacement Noun
[dis-pleys-muhnt]
Back
Displacement
The change in an object's position, represented as a vector quantity pointing from the initial to the final position.
Example: This diagram shows that even after traveling a 5 km distance to school and back, the total displacement is zero because the starting and ending positions are the same.
5.
FLASHCARD QUESTION
Front
Uniform Motion Noun
[yoo-nuh-fawrm moh-shuhn]
Back
Uniform Motion
Movement of an object at a constant velocity, meaning it travels in a straight line with an unvarying speed.
Example: This distance-time graph shows a straight line, meaning an object covers equal distances in equal time intervals, which is the definition of uniform motion.
6.
FLASHCARD QUESTION
Front
Parabola Noun
[puh-rab-uh-luh]
Back
Parabola
The characteristic U-shaped curve of a position-time graph for an object moving with constant, non-zero acceleration.
Example: A basketball thrown towards a hoop follows a curved path called a parabola due to the constant downward pull of gravity.
7.
FLASHCARD QUESTION
Front
Average Acceleration Noun
[av-er-ij ak-sel-uh-rey-shuhn]
Back
Average Acceleration
The total change in an object's velocity divided by the total time interval over which that change occurred.
Example: A car slowing down for a speed hump is an example of negative acceleration, as its velocity decreases over time.
