Newton’s second law of motion prompts that there is no state of balance between the action of objects and the existing force that surrounds them .It also argues that the speed of an object is reliant on two variables, the net force acting on an object and the mass of an object…

"Source of error"

Download file to see previous pages It is expressed by the equation:
A source of error is described as any factor that affects the final result of an experiment. However, careful evaluation of a source of error makes it possible for experimenters to improve on their techniques.
One source of error in Newton’s second law of motion is found in the incomplete definition, this is because gravitational force usually causes mass to speed up. In Newton’s definition, he excludes mentioning the effect of gravitational force as a co-effect to the variables. Therefore Newton’s law can also be expressed as;
Secondly, a source of error found in the law is the systematic failure to account for constancy in change as the net force changes. It is predicted that the speed of an object mass increases constantly when the net force acting on the object itself changes. For example in these calculations;
In addition, the third source of error in this law is found in the systematic or random environmental factors where Newton did not account for possible effects of environmental condition for instance temperature and how they affect the final results. For example when measuring the mass of a stone, we avoid highly ventilated rooms and use small strings on a pulley instead of large ones to minimize the percentage error.
Moreover, parallax and experimental apparatus errors is a common source of error in experiments, for instance when the observers eyes is not in proper alignment with the scale the mass recorded will be faulty. It is advisable to use the null difference method instead of measuring mass directly thus creating a sensitive measuring instrument.
Finally, a source of error in Newton’s law involves the rate of variation of a body which is directly proportional to the applied force and follows the direction where the force acts upon. This force as earlier said is not in ...Download file to see next pagesRead More

Effective Spring Constant
For each configuration, we suspended a number of masses on the spring system and measured the displacement of the setup from its original position. We’d then find out the effective spring constants graphically by plotting the graph between the force applied and displacement of the system.

Lab Report - Precision and Accuracy
Another possible source of differences in terms of precision is the possible time that elapsed in the pipetting of the solution for each trial. For one reason or another, the elapsed time may have caused slight evaporation in the liquid solution. Another thing is the possibility that the temperature of the transferred solution or the temperature of the laboratory slightly changed for every trial and so it may have slightly affected the rate of evaporation of the delivered liquid.
