The computer program then averaged this range of data chosen by us. An average of data will be different than an almost instantaneous acceleration of a particular mass being pulled upon by a constant force.
Analyzing the graph of constant mass shows that as the applied force was increased, acceleration also increased.
Verifying Newton’s Second Law
The positive, linear slope shows that there is a direct, linear relationship between acceleration and force. This agrees with the mathematical equation, since a constant mass is being divided into a larger numerator, or force, acceleration should increase. These differences could be attributed to two factors: To increase applied force, we had to increase the mass of the system. Note the relative increase in values of acceleration as the slotted mass is increased.
Investigating Newton's second law of motion
The relationship between acceleration and applied force is investigated more precisely by plotting an XY graph of these two quantities. Use a curve-matching tool to identify the algebraic form of the relationship. This is usually of the form 'acceleration is proportional to the applied force'.
This relationship is indicative of Newton's second law of motion. The great advantage of this version is that the software presents acceleration values instantly. This avoids preoccupation with the calculation process, and greatly assists thinking about the relationship between acceleration and force.
The Mighty F = ma
Each repetition with the same force gives a similar acceleration. If the force is doubled, this results in a doubling of the acceleration, and so on.
The uniform increases in the acceleration can be confirmed by using cursors to read off corresponding values from the graph. The quality of the fit is reduced if the suggested procedure for maintaining the total mass constant is ignored. Also, a common outcome is a very small intercept near the graph origin.
The most likely cause of this is neglect of the effect of friction on the motion of the trolley. This may be conducted to provide data for the complementary relationship indicated by Newton's second law: The value of the slope is 0.

This simplifies to kg. The slope represents the mass of the pulley. What is the total mass of the system both with and without extra weight that you measured?
The total mass of the system without the extra weight was 0. How does the slope of your graph compare percent difference with the total mass of the system that you measured?
