Below is a summary of the data collected by each lab group as they sought to determine the how affects the period of a pendulum/spring oscillator.

PENDULUM - Period vs. Amplitude

PENDULUM - Period vs. Length

PENDULUM - Period vs. Mass

SPRING - Period vs. Amplitude

SPRING - Period vs. Length

SPRING - Period vs. Mass

Today March 16th in Class

Today in class we analyzed the data that we collected in class into a table that looks like this:

Length

Amplitude

Mass

Mass on Spring

As length increases period increases

As amp. increases period stays the same

As mass increases period increases

Pendulum

As length increases period increases

As amp. increases period stays the same

As mass increases the period stays the same

Next, we discussed the meaning of the words period and frequency. We created a chart with things that we do once a second, a day, a week, a month, and a year. This eventually gave us two equations that look like this

>PERIOD (T) = amount of time/ number of events (unit=seconds)

>FREGUENCY (F) = number of events/ amount of time(unit=cycles/second or HZ(Hertz))

The chart above and the equations listed sums up everything we learned in class today.

Today we went to the science computer lab to work on our first webassign, but before that we had a demo. The slope of the line the data makes is called the spring constant or k. The spring constant in this case if . We also learned that PE=, where x is the distance squared. Then we had a QOD asking what the velocity would be of a cart weighing 0.5kg, and we has to use Conservation of energy and make PE=KE then solve for velocity.
