Overview:
In this lab we will use your video for the free fall to verify the conservation of energy/ Work-Energy theorem. We will verify that
weight as a conservative force, offers the opportunity of conversion of potential gravitational energy into kinetic energy. For
this purpose, we will be calculating g and comparing it to the accepted value.
We will also consider the accepted value of the acceleration due to gravity to be:
g = (978.03 ± 0.01)cm/s?
Conservation of Energy:
As your object falls, its position as well as its speed changes. The video analyzer "Tracker" will give the position and the speed of
your object.
Since your object started from rest:

Wmg = mgh = AKE =
mgh-ΔΚΕ :

v? = 2gh
1. What should we plot to get a linear graph? What are your predictions for the slope?
2. Plot your data using Excel (attach a copy of your graph, make sure to label the axis and add a title to the graph). Add a
labeled table of data to your Excel graph sheet.
