Physics lab report guidelines summary the following is an outline of the requirements for a physics lab report a experimental description 1 provide a statement of the physical theory or principle observed during the exper. 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 sheet to design a table for my results me and my lab partners clamped a recording timer in a vertical position. For example, if you determine from an experiment that the acceleration due to gravity is 10 m/s 2 then the 'error' is the difference between that value and the accepted value of 98m/s 2 , or 02m/s 2. 9/16/14 physics 01l density abstract this experiment was conducted in order to determine the density of the aluminum metal samples provided in the lab specific tools such as the vernier caliper and balance scale were used to measure and record the values found. 3bring to each laboratory session experiment 1-0 to go over the experiment to describe the equipment to be used and to outline the important issues.
This means that if an object were dropped from rest, after one second it would have a velocity of 98 m/s, after two seconds its velocity would be 196 m/s, and so forth there are two parts to this experiment. Physics 1200 iii - 5 pre-lab for lab#3 problem 2 at a picnic, there is a contest in which hoses are used to shoot water at a beach ball from three different directions. 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 method : an experimental pendulum is suspended successively about several axes at different points along its length and the period about each axis is observed. To determine the best value of g, use all your data together by fitting make a plot of period squared (on the y-axis) vs length (on the x-axis), using averages of the 20 swings with the 10 different pendulum.
Suppose you obtained a value of 995 m/s 2 for g from a second experiment to compare this with the result of 102 m/s 2 from the first experiment, you would calculate the percent difference to be. We could look up the accuracy specifications for each balance as provided by the manufacturer (the appendix at the end of this lab manual contains accuracy data for most instruments you will use), but the best way to assess the accuracy of a measurement is to compare with a known standard. A thread a length of ticker-tape through a ticker-timer and attach the end to a trolley b pull a trolley with a fixed force along a benchloop one end of the elastic cord around a rod attached to the trolley. To use this equation to calculate the acceleration, all of the forces acting on an object must be added, in a vector sense, to get the total force acting on the object.
If you are working in a lab or in the field, do not work alone this book assumes that you will read the safety precautions that follow, as well as those at the start of each experiment you perform, and that you will remember them. To determine which measurements weremost reliable, data was taken for the period of the rst oscillation, second oscillation, and twenty oscillations (omitting the rst) at a set length of 20098 cm. Purpose the purpose of this lab experiment is to study the behavior of springs in static and dynamic situations we will determine the spring constant, , for an individual spring using both hooke's law and the properties of an oscillating spring system. From data table b above, calculate the average time, the square of the average time, ratio d/t avg 2 and the ratio h/l for each of the four heights divide the two ratios from table b (divide d/t 2 by h/l) and enter the results in the table b1 below.
Table is used to de ne the acceleration due to gravity, g, the initial horizontal and vertical coordinates of the object's position (x 0 and y 0 ), and the corresponding initial velocities (v x0 and v y0 . Further, any physical measure such as g can only be determined by means of an experiment, and since a perfect experimental apparatus does not exist, it is impossible even in principle to ever know g perfectly. Surface to determine whether the surface area of the block or the type of surface affects friction we found that the surface area of the block did not change the coefficient of kinetic friction, while the types of materials in contact were directly related to the coefficient of kinetic friction.
Final lab grade will be based on your lab logbook (see the first chapter of these notes) as well as two written reports that will be completed over the course of the term (unless otherwise noted in your syllabus. Data with your lab partner and discuss all aspects of the experiment however, you are not to share experiment 1 velocity, acceleration, and g he found that the. Extract physical constants from polynomial and linear fits to data use the kinematic equations to relate time, position, velocity when acceleration is constant percent error. 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 this number to determine how good the fit is.
To identify the correlation between the movement of the cart and the appearance of the velocity time-graph and use that correlation to calculate the displacement and acceleration of the cart 1) a table was drawn to record time, displacement and average velocity 2) the ramp, recording timer and. Acceleration as one of the most fundamental parameter in physics by using these easy-to-have and easy-to-use everyday tools the theoretically backgrounds of the experiments range from the simple use of the law of gravitation to the. 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 different gravitational environments by selecting an environment from the drop-down environment menu. Data acquisition: using two photogates, the instantaneous velocities found can be used to calculate an average acceleration in turn, this average acceleration can be used to calculate an experimental value for the mass of the cart.
