Interpreting Graphs

Front

What is the definition of speed in the context of motion?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s).

Front

How do you determine the speed of an object from a graph?

Back

The speed can be determined by calculating the slope of the distance-time graph.

Front

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

Back

A horizontal line indicates that the object is stationary.

Front

What does a straight diagonal line on a distance-time graph represent?

Back

A straight diagonal line represents constant speed.

Front

How do you write an ordered pair for a point on a graph?

Back

An ordered pair is written as (X,Y), where X is the value on the horizontal axis and Y is the value on the vertical axis.

Front

What does a steep slope on a distance-time graph indicate?

Back

A steep slope indicates a fast speed.

Front

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

Back

The y-intercept represents the initial position of the object at time zero.

Front

How can you tell if an object is accelerating from a graph?

Back

An object is accelerating if the slope of the distance-time graph is increasing.

Front

What does a curve on a distance-time graph signify?

Back

A curve indicates that the speed of the object is changing.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.
