3rd Hour Homework

Using the data from the pendulum lab, graph ONLY THE MEAN (average) of each trial with 1 washer, 2 washers, and 3 washers. At the bottom of your graph write the following sentence and fill in the blank: “As the number of washers increased, the distance the box traveled ______________________. (Did it increase or did it decrease)?

Observe the following picture and fill out the graph on the back of the worksheet using the data table given.

Vocabulary words you need to write on the back underneath the table:

Speed- distance traveled per unit of time. Speed= distance/time

Velocity- distance traveled per unit of time AND DIRECTION. Velocity= distance/time + direction.

What happens to the velocity as they drop the pendulum from 3cm to 7cm to 12cm?

What happens to distance the box moved as they dropped the pendulum from 3cm to 7cm to 12cm?

If height increases potential energy, and potential energy turns into kinetic energy, what happens to speed? Is it increasing or decreasing as the pendulum is released?
