"Walking, Falling ..."

Today, I passed out grade sheets. These grade sheets should be shown to your parents, signed, and returned for a stamp. All entered grades for our class can be seen, including the most recent test and quiz. Those graded tasks will be returned on Wednesday. I am just waiting for everyone to have taken them.

We went over "Walking ..." from last Wednesday. This handout introduced the concepts of rate of change and average rate of change. We investigated how Dwain's speed remained constant at 4 feet per second, while Bryan's speed changed each of the first 5 seconds. However, they both ended their race in a tie.

We ended class by starting "... Falling ..." Remember, although there is a constant change to the speed of the falling ball, it is still a changing speed. It has a constant increase or acceleration of 9.4 (this is the acceleration due to gravity on Earth). The formula to calculate the average rate of change is:

change in distance

change in time
