1.2 Flashcard Representing Rates

Front

What is a rate in the context of distance and time?

Back

A rate is a ratio that compares two different quantities, such as distance traveled per unit of time (e.g., meters per second).

Front

How do you read a distance-time graph?

Back

A distance-time graph shows how far an object has traveled over time. The x-axis represents time, while the y-axis represents distance.

Front

What does a flat line on a distance-time graph indicate?

Back

A flat line indicates that the object is not moving; the distance remains constant over time.

Front

How can you determine the speed of an object from a distance-time graph?

Back

The speed can be determined by calculating the slope of the line on the graph. A steeper slope indicates a higher speed.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

If a person travels 10 meters in 2 seconds, what is their speed?

Back

Speed = 10 m / 2 s = 5 m/s.

Front

What does it mean if an object takes longer to travel the same distance?

Back

It means the object is moving slower, resulting in a lower speed.

Front

How do you find the total distance traveled from a distance-time graph?

Back

You can find the total distance by looking at the highest point on the graph or by calculating the area under the line.

Front

What is the significance of the y-intercept in a distance-time graph?

Back

The y-intercept represents the starting distance of the object at time zero.

Front

How can you identify stops in a journey on a distance-time graph?

Back

Stops are indicated by flat sections of the graph where the distance does not change over time.
