Introduction to Measurements & Error Analysis The Uncertainty of Measurements Some numerical statements are exact: Mary has 3 brothers‚ and 2 + 2 = 4. However‚ all measurements have some degree of uncertainty that may come from a variety of sources. The process of evaluating this uncertainty associated with a measurement result is often called uncertainty analysis or error analysis. The complete statement of a measured value should include an estimate of the level of confidence associated

Kathryn Marchessault Physics Lab LR Tuesday 8-9:55 Due 02/26/15 Experiment #1 Free Fall Experiment Abstract In this experiment we studied the motion of an object in free fall‚ that is an object being dropped from a certain height to Earth’s surface. In this experiment we tested the idea that no matter what the size‚ shape‚ color‚ etc. of the object if it would still experience the same constant acceleration throughout its fall (short distance). The constant downward acceleration it experiences

The lesson is divided into 3 labs that can be completed in any order. After labs have been completed‚ facilitate a class discussion where students summarize and compare findings and relate how their findings support (or refute) Newton’s Laws of Motion LAB 1: How fast can it go? Put one car at the top of the ramp and let it roll down. Use a stopwatch to record the time the car rolled. Use this information to calculate the acceleration of the car. Measure the distance the car rolled using the

Purpose Determine the acceleration in a quick sprint. Question What would the participant’s acceleration be if he/she sprints forward in a positive direction? Hypothesis/Prediction When a person sprints forward‚ it means he/she speeds up. Consequently‚ the acceleration should be positive. When the velocity accelerates at a constant rate‚ the acceleration should remain constant. Therefore‚ if the participant is moving toward a positive direction and the speed increases‚ then the acceleration

Lab:Measurement Error (Bounds) Purpose The purpose of this experiment was to understand and recognize that errors do occur when doing experiments and making measurements. With this lab we had to understand how to analyze the data using measurement bounds. Theory: In this experiment we were to find the density of the wood we are measuring by using the method of upper bound and lower bound. Density is a physical property of matter. Every element and compound has its very own unique density

Percent Error occurs due to many factors. In this lab by the graph I can state that there was a 100% error in all three unknown substances‚ Pure Leaf Lemon Tea‚ Sprite‚ and Tree Ripe Lemonade. This could be a result of not having properly zeroed the scale or the scale glitching when it came to zeroing it‚ which would have added extra mass and skewed the results. Another factor that could have resulted in a high percent error would have been the scale itself glitching which would have caused the wrong

wavelength is represented by the formula v= ƒλ ‚ 1) Raw data presented Table 1 Table 1 shows the frequency of the different tuning forks and the length of air needed for maximum resonance. The error on the length was estimated to 0.1 cm as we repeated eachexperiment several times. Note the error on the forks’ frequencies is a mere estimation as theyare accurately calibrated during manufacture.

Miriam Karunakaran Physics Honors Period 6 Physics Kinematics Lab Report Kinematics is the study of the motion of bodies without reference to mass or force. This lab aided students in observing kinematics by giving them a visual graph to look at from experiments previously performed. Variables used in this lab were “x” for position of the object‚ “v” for velocity of the object‚ and “a” for acceleration of the object. Understanding the graphical representation of
