Question

Laboratory 6-Measuring g Objectives By the end of this lab, you should be able to evaluate whether an experimental value is signif able to identify ways to improve an experimental different from a theoretical value. You should be setup and test whether these improvements actually do improve your data. Equipment LabPro, photogate, carts, frictionless track, smart pulley, level, string, masses, electronic scale/tripl beam balance Introduction It is known that the acceleration due to gravity is 9.80665 m/s? but have you ever wondered how you can de value. You will have uncertainties associated with your values and thus with your final result. Th actual value that you are trying to achieve should lie within your error range in order for the lab to be called a success. If it does not, this should be commented on and explored. termine this value? In this experiment, you will be comparing your results against a known Theory Newton's 2nd Law is expressed as where Foet is the net all the forces acting in a system. (Vector summation means that direction matters) force, m is mass, and a is acceleration. The net force is the vector summation of By combining these two equations we get the equation This equation applies to each object separately. It would be a good idea to construct free body diagrams to help find all the forces acting on each object. Then you can determine an eq using the power of algebra. uation for g Procedure & Analysis The materials that are at your disposal are LabPro, a photogate, a cart, a frictionless track, a level, strin g, masses, and an electronic scale or a triple beam balance. Tie/tape a string to the end of the cart. Then lead the string over the smart pulley and attach a mass to the end. With the apparatus set up, you need to determine the acceleration of the masses can calculate the acceleration due to gravity using the equation you derived. using LoggerPro. From this acceleration you

Explanation / Answer

In our experiment we are not considering AIR DRAG(a force which is proportional to velocity and acts opposite of motion of body, it depends on shape of moving body also). As it acts in opposite of motion, so our value will be LOWER THAN true value.
