Distance Time Graphs Explained

Miss EES introduces the concept of motion and how it can be represented on distance-time graphs. The video covers plotting points on a graph, understanding the axes, and interpreting different types of motion such as constant speed, rest, and returning to a starting point. Students are guided through examples and practice problems to reinforce their understanding of these concepts.

What is the definition of motion?

• When an object changes position over time relative to a reference point.

• When an object changes shape over time.

• When an object remains stationary.

• When an object changes color over time.

What are the coordinates of the first point to plot on a graph?

• (4, 8)

• (1, 1)

• (2, 4)

• (0, 0)

On a distance vs. time graph, what does the x-axis represent?

• Distance

• Energy

• Speed

• Time

How far does a squirrel run after 1 second if it moves at a speed of 2 m/s?

• 1 meter

• 4 meters

• 2 meters

• 3 meters

If an object is moving at a constant pace, how will the distance vs. time graph look?

• A curved line

• A horizontal line

• A straight line at an angle

• A vertical line

What does a horizontal line on a distance vs. time graph indicate?

• The object is moving at a constant speed.

• The object is at rest.

• The object is accelerating.

• The object is decelerating.

What happens to the graph when an object returns to its starting point?

• The line goes downwards.

• The line goes upwards.

• The line becomes vertical.

• The line remains horizontal.

Which story best explains a graph where the line goes up, then down, and then up again?

• Liz walked to her friend's house, stopped for a few hours, and walked back home.

• Michelle walked to the mailbox, walked back a little, and then went back to the mailbox.

• A squirrel ran at a constant speed.

• Katie stopped to look at the stars.
