Linear Motion Diagram
Now Linear Motion Diagrams are new to us and are a simple what of showing velocity and acceleration. First, you must determine if the object is increasing, decreasing, or constant for the time interval you are answering questions to. Then, you have to sketch the object and then write the motion above the object. However, only one motion can be written per object so only write one. Finally, the most important part is correctly labeling the velocity and acceleration. The arrows represent the direction of the velocity and acceleration. A helpful hint is to remember the arrows go the same way if the object is speeding up. If it is slowing down then the arrows go in the opposite direction.

Accelerometer
[|accelerameter.jpg] This part is extra credit. By **Thursday** take a jar and fill it with water. Then put a piece of cork on a string and hand the string on the lid of the jar. Then when you seal it and turn it upside down. Also, be able to see which way the cork goes when you go around a turn. This works by displacement. When you turn put it in motion the water wants to stay in place. So all the water rushes back towards one side causing a vacuum on the other side. The cork is pulled in this direction and makes the accelerometer work.
