Calculate the average value of l/t 2 for the various choices of t, and then calculate g as in step 2 above determine k g and i g as outlined in steps 3 and 4 above repeat the experiment in. Experiment 2 measurement of g: use of a simple pendulum with the help of a lab partner, set the pendulum in motion until it completes 30 to period of a simple pendulum depends only. This will be used to calculate the centripetal force acting on the mass m as it rotates around the spreadsheet data tables for experiment vi: centripetal force and acceleration physics. The experiment is to enable the students to observe the image formed of an optical pin in the glass block and also use the data obtained to determine the refractive index of the glass block. To do this, use a magnetic compass to determine the direction of the earth's field, mark its direction on your work station with paper tape, and record its coordinates also measure and.
Further, any physical measure such as g can only be determined by means of an experiment, and since a perfect experimental apparatus does not most experiments use theoretical formulas. Apparatus and materials trolley elastic cords for accelerating trolley rod for attaching elastic cord to trolley ticker-timer with power supply unit ticker-tape sellotape acceleration, a. Acceleration is a change in an object's state of motion a few variables need to be identified to calculate an object's acceleration, but once we have those values, we can put them into a. In the following we wish to use this equation to determine the local acceleration due to gravity g based on a pendulum experiment solving for g we obtain: this leads to the following.
Experiment 6 the spring constant determination models to describe physical systems by using observational and experimental data we then use these models to either explain previously. Here is how to calculate the mean or average of a set of numbers among other things, this will allow you to calculate your grade point average learn how to calculate the mean, median. In the first part, the students will replicate galileo's original experiment, using an inclined plane to measure the acceleration of an object only one object, a marble, will be used in. Use the statistics option to determine the mean value of the force while the mass is being held stationary report the mean value of the force (tension) measured by the force sensor in the.
For example, in an experiment to calculate acceleration due to gravity using the length and time period of a simple pendulum, the size of the pendulum bob, the air friction, the slight. Is head injury caused by linear or angular acceleration albert i king, king h yang, liying zhang and warren hardy acceleration, even though both are present in any head impact in a. Physics lab report guidelines data for every lab experiment your graphs will be linear functions for most experiments there may be a few graph plots that make use of diﬁerent. The purpose of this experiment was to examine kinetic friction and what factors affect it we affects friction we compared the coefficients of kinetic friction for different surface.
Wku university physics laboratory i-3 how to write a lab report how to write a laboratory report and the main results of the experiment if a known physical quantity was measured in the. The purpose of this lab was to evaluate the increase in velocity with time during a free fall also, to determine the position from the start of the fall i used the table on the given lab. And provides tools to aid design of physical experiments and sensors practical problems arise involving two different configurations: k b m can be found in pre-lab readings (ogata.
This means that it calculates for each data point the square of the difference between that data point and the line trying to pass through it it then adds up all these “squares” and uses. The data section includes all the raw data you collected in the laboratory without any calculation or interpretation at a minimum, include the following information.
Physics 1291 general physics i lab columbia university department of physics fall 2011 contents 1 purpose of the laboratory the laboratory experiments described in this manual are an. The aim of the experiment was to determine the value of the acceleration due to gravity by measuring the period of the simple pendulum effects that the length of the string and the mass of. ® physics 1 and 2 inquiry-based lab more than just learning about our physical world it also requires practices that are “used to establish, extend, and refine that knowledge” over time. The objective of many experiments in physics is to determine the value of a well-known physical quantity (eg the acceleration of a falling object due to gravity) experimental.
