so. We repeated this measurement‚ using the same initial height‚ four more times. Then we took the masses and the wingnuts off the horizontal rod and let the 0.2 kg mass fall in the same way as before‚ five times. Then we replaced the masses and the wingnuts‚ but put them both on the edges of the horizontal rod‚ and repeated the same falling mass measurements five times. We moved the masses in towards the centre of the rod and continued to repeat the falling mass measurements. We moved the masses

Introduction: Measurement is the collection of quantitative data. The proper handling and interpretation of measurements are essential in chemistry and in any scientific endeavor. To use measurements correctly‚ we must recognize that measurements are not numbers. They always contain a unit and some inherent error. We define precision as to how well experimental data and values agree with each other in multiple tests. Another important concept when dealing with measurements is accuracy‚ which

LAB 02: Measuring and Dispensing Liquids Introduction Pipetting is one of the most important and basic skills when it comes to experimental science. Good pipetting skills allow an individual to put trust in his or her results‚ prevent waste of materials‚ and assure reproducibility of results. In order to correctly pipette liquids‚ the volume range must be first determined. p1000 micropipettes have a volume range of 200 - 1000 uL‚ p200 micropipettes have a volume range of 20 - 200 uL‚ and p20 micropipettes

In conclusion the pressure calibrator and temperature calibrator were proved to be accurate in their measurements through the use of plots‚ data analysis and statistical analysis methods.

Abstract- The development of De-Sauty’s bridge for capacitance measurement has been followed by various modifications and improvements in the original circuit. Lately Schering bridge and transformer ratio arm bridge have been used for measurement of capacitance in a circuit.Today there is instrumentation available that makes use of these bridges in real life such as that can measure the quality of electrical insulation at power frequency as well as in touch-sensitive sensors.

Measurement Devices Objectives: • To know how to use the different measuring devices properly. • To know how to solve the volume. • To know how to solve the Density. Introduction: "Accurate measurement is essential" – Measurement is the size‚ length‚ or amount of something‚ as established by measuring. Measurement is the first step that leads to control and eventually to improvement. If you can’t measure something‚ you can’t understand it. If you can’t understand it‚ you can’t control it. If

Objectives The main objective of this experiment was to determine the spring constant using the dynamic method. 2. Theoretical fundamentals On the one hand‚ when a spring oscillates‚ the movement which describes can be classify as a simple harmonic motion. Therefore‚ its position‚ velocity and acceleration equations respect the time will
