Front

What does it mean when a graph shows that an object is not moving?

Back

It means that the object's position is constant over time, indicating zero velocity.

Front

What is a function in mathematics?

Back

A function is a relation where each input (x value) has exactly one output (y value).

Front

How can you determine if a set of ordered pairs is a function?

Back

Check if any x value repeats with different y values; if it does, it is not a function.

Front

What does it indicate if a table has an x value that corresponds to multiple y values?

Back

It indicates that the relation is not a function.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object over time.

Front

What does it mean for an object to travel at a constant speed?

Back

It means the object covers equal distances in equal intervals of time.

Front

What is the significance of a steep slope in a distance-time graph?

Back

A steep slope indicates a high speed or rapid movement of the object.

Front

What does a flat line represent in a distance-time graph?

Back

A flat line represents that the object is at rest, not changing its position.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What does it mean if a graph shows a decrease in distance over time?

Back

It indicates that the object is moving back towards the starting point or slowing down.
