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
