Next, to find their uncertainties, you must determine how to get the uncertainty in the natural logarithm of a quantity from the original uncertainty in the quantity.

Use the protractor to precisely determine these angles of release. And, despite our non-ideal laboratory conditions, we may still expect to see this trend in our data.

One suggestion is to take even increments, measuring the Physics pendulum lab report at string lengths of 10 cm, 20 cm, 30 cm, … up to cm.

You can do this by following the general uncertainty propagation formula provided in the uncertainty guide. Does the accepted value of 2 fall within your experimentally determined estimate? What sources of error might have affected your results?

Then, to find the uncertainty in your slope value, draw in lines with the maximum most steep and minimum least steep slopes possible that still pass through the error bars of most of your data points, as well as the origin at 0,0. If not, use a stopwatch.

You will also begin to learn how to find, investigate, and understand major sources of uncertainty and error in measured and calculated quantities. Factors to take into account should include the scale on your measurement tool, and how accurately you can determine the center of the ball and the pivot point.

Begin by considering the uncertainty in your measurement of the time for ten oscillations. How accurately do Physics pendulum lab report think you can press the button to tell the computer when to start and stop the measurement?

By taking an average value, you will reduce the effects of making a single unusually high or low measurement. Make sure that you understand how to get this equation from the equations in your uncertainty guide! Procedure For this experiment, you will conduct two analyses: Discuss this in your lab report!

If the mass is NOT carefully set into motion, it becomes a conical pendulum, which does not swing along a vertical plane and is, therefore, a more complicated physical system.

Take the difference between your stop time for example, Since your reaction time affects both the start time and the stop time, these uncertainties are sources of random error, and they add in quadrature so that: One approach you can take is to first measure the length from the center of the ball to the center of the pivot directly.

What aspects of the setup or methods can be improved to obtain more accurate or precise results? For the first measurement, you will test this expectation by finding the period of oscillation at 3 different angles of release: For the purposes of this experiment, you will need to ensure that your simple pendulum swings in a vertical plane.

Do this for 10 different lengths of the string. Explain why your results make sense, based on our assumptions of the simple pendulum. Now, you will find your own reaction time by starting the timer, and attempting to stop it at exactly Sample lab procedure and report The Simple Pendulum In this laboratory, you will investigate the effects of a few different physical variables.

Play with one or two pendulums and discover how the period of a simple pendulum depends on the length of the string, the mass of the pendulum bob, the strength of gravity, and the amplitude of the swing.

Observe the energy in the system in real-time, and vary the amount of friction. Measure the period using the stopwatch or period timer. Use the pendulum to find the value of g on Planet X.

The experiment was carried out to show that the mass of the bob has no effect on the period of the oscillation. In the experiment, both the length and the mass of the bob were varied. Other variables such as the angle of displacement were kept.

Lab Report Compound Pendulum in Different Medium Words | 6 Pages Lab Report Compound Pendulum in different medium Raoul Corstjens IS10a Introduction An oscillating object is a mass that follows a pattern that causes the mass to return to its initial position after completing one complete oscillation in a constant certain amount of time.

If you try to time one oscillation of the pendulum, you will find that it is fairly difficult to get a single accurate value after multiple attempts.

Investigating the Effect of String Length on Pendulum Period IB Physics SL Period 3. Ding 2 I will be investigating the effect of the length of a pendulum’s string on the time for the period of that pendulum. Given my previous knowledge, I know that a pendulum behaves in an to conserve paper on the lab and also because I believe that.
