Motion in One Dimension
The study of Newtonian Mechanics begins with studying
the one dimensional motion of objects. This is most easily
done by observing and measuring the characteristics of objects
that are dropped from some height.
This week we will be doing some physical experiments as
well as some JAVA applets that are designed to have you
measure the motion of falling objects.
The only quantities that you will be able to measure are:

Time

Length
With measurements of time and length you will be able to
compute velocities, accelerations and energies. From
this information you will be able to make predictions.
The basic experimental procedure will be to:
- Drop objects of different mass from different
heights and measure when they pass fixed reference points:
- Determine which objects have the most energy when they
hit our "energy detector" at the bottom. You will have to
aim well for this.
You will record your data on regular paper but then will transfer
all this data to the electronic lab book
when it is ready. Your identifier for your own lab book will be the last
4 digits of our student number.
