Do Now: Yesterday we did this -

DISTANCE-TIME GRAPHS

A distance-time graph tells us how far an object has moved with time.

The steeper the graph, the faster the motion.

A horizontal line means the object is not changing its position - it is not moving, it is at rest.

A downward sloping line means the object is returning to the start.

And we drew this Speed-Time graph:

SPEED-TIME GRAPHS

A speed - time graph shows us how the speed of a moving object changes with time.

The steeper the graph, the greater the acceleration.

A horizontal line means the object is moving at a constant speed.

A downward sloping line means the object is slowing down.

Why it matters in THIS CLASS: Unit #1-2 Exam this Thusday, October 2, 2014.

BE PREPARED!

Why it matters in LIFE:We interact with velocity and acceleration every day. Understanding how to read graphical interfaces helps to develop your abstract reasoning skills.

By the end of the day today, IWBAT…• Analyze characteristics of graphs and interpret differences in velocity & acceleration.

Graph Matching Activity

You have several graphs in front of you

Select the Information that accompanies each graph and match them together

Once you have the correct matches, you will create a notebook foldable to study

If You haven’t finished your Post-It note Fold-Ups!

On the Post-It Notes, draw the graph outline, then stick onto a piece of paper.

Underneath, write the important facts about the graph.

You can flip up the Post-Its when you study, checking the details for each graph underneath.

Create Your Own Graphs

Now create your own situations to graph – use a runner, a car – whatever!

Then the class will draw: a DISTANCE vs. TIME GRAPH a VELOCITY vs. TIME GRAPH

Create Your Own Graphs

Create two graphs that show a runner’s path: He travels UP a STEEP hill, then DOWN a STEEP hill, then ACROSS a FLAT plain. Think about what he would look like and make:

a DISTANCE vs. TIME GRAPH a VELOCITY vs. TIME GRAPH
