Check this by shaking/tapping the connecting wires lightly at each part of the circuit and observe the ammeter’s reading. Replies. CSEC® is a registered trade mark of the Caribbean Examinations Council (CXC). experiment 10: Compound Pendulum OBJECT: To study the properties of a compound pendulum, and to determine the acceleration due to gravity by the use of such a pendulum. �t��Z�Z?/ �h����M Measurement, Mechanics, Practical Help, Scientific Method. The simple pendulum can be viewed as a point mass and is a resonant system with a single resonant frequency. 337 0 obj <> endobj <]>> Here is a summary of some of these sources of errors and how to avoid them. official was 'distracted' during fatal crash. © 2020 SmartStudy Solutions — Powered by WordPress. The most common source or errors in the diffraction grating experiment is in taking the measurements. Place the pins vertically upright (Check with a set-square), Place the the pins used to locate the path of the light ray more than 6 cm apart to minimise errors (Check that pin-pricked points are clearly marked and labelled), Use the view from the base of the pins when aligning pins in a straight line as the pins may not be perfectly upright, Measure the object and image distances along a line parallel to the principal axis. endstream endobj 372 0 obj<>/W[1 1 1]/Type/XRef/Index[23 314]>>stream endstream endobj 338 0 obj<>/OCGs[340 0 R]>>/PieceInfo<>>>/LastModified(D:20061122164118)/MarkInfo<>>> endobj 340 0 obj<>/PageElement<>>>>> endobj 341 0 obj<>/Font<>/XObject<>/ProcSet[/PDF/Text/ImageC/ImageI]/ExtGState<>/Properties<>>>/StructParents 0>> endobj 342 0 obj<> endobj 343 0 obj<> endobj 344 0 obj<> endobj 345 0 obj[/ICCBased 366 0 R] endobj 346 0 obj[/Indexed 345 0 R 255 370 0 R] endobj 347 0 obj<> endobj 348 0 obj<>stream

Measure the value of g? 0000006465 00000 n We are also calculating kinetic energy and gravitational potential energy.
calculate the length and compare it to the real length? 0000006837 00000 n If the reading fluctuates, it means there is a bad connection in the circuit, Make sure there is no ‘kink’ in a bare resistance wire especially when you have to measure the length of the wire accurately, Switch on the circuit for a few seconds before taking a reading and then switch it off immediately. (Make sure that starting temperature for both experiments are the same), Avoid heat transfer by convection by switching off the fans and closing windows and doors, Use lids where possible to reduce heat loss by convection.

Put your eye directly above the pointer such that the reflection of the pointer in the glass cannot be seen or they both line up, Tighten the contacts between the wires and the components to reduce contact resistance in the circuit. it’s not possible to conduct a perfect experiment. Having inaccurate instruments or estimating the measurements can cause errors.

its for conservation of energy. The bar can be hung from any one of these holes allowing us to change the location of the pivot. 0000008052 00000 n There are sources of error in measuring the period, but those can be minimized by various means, such as measurement over many periods, or photocell and counter methods.

startxref Experiment 9: Compound Pendulum A compound pendulum (also known as a physical pendulum) consists of a rigid body oscillating about a pivot. We are also calculating kinetic energy and gravitational potential energy. Still have questions? The Universe cant magic into existence, it has to have a cause.
a glacier moves a the rate of 43.0 meters per year.
If it has a cause, it can only be eternal? The contact resistance at the joint can be quite significant. Sources of errors in mechanics experiments. Reply. How would time flow if we stayed absolutely still. They make for good material to put in the discussion part of the lab report and usually indicate that you have a fair understanding of the limitations of the particular physics experiment that you were doing.
