Velocity and Time Graphs

We started the day off with taking a quiz on displacement and distance and time graphs.

We learned how to do a velocity and time graph.

From the left of the graph 0-10 seconds shows that it is accelerating. From 10 to 15 seconds it is going a constant speed of 60m/min. From 15 to 30 seconds it is slowing down and at 30 seconds comes to a stop. From 30 - 40 seconds it changes directions and speeds up. From 40- 50 seconds it slows down.

We also learned that to find the displacement you divide the lines and the 0m/min line into triangles and rectangles using the formulas 1/2bh and lw. Once you get the numbers for the sections you addd them together. If the line goes below 0m/min tha you would subtract that section from the secton that is above the line.

We also learned how to switch a distance and time graph into a velocity and time graph and that they would look different but mean the same.
