The objective of the experiment was to understand the relationship between forces,masses and acceleration by measuring the acceleration of the cart caused by aweight attached to a string. The objective was completed because I now have abetter understanding on how friction works in Newton’s Second Law. Force isconstant for the rolling of the cart and the acceleration is equal to the slope of thevelocity vs. time graph. For the measured and calculated tension, my percent errorwas typically small except for the second trial. This could be due to human errorwhen measuring and calculating the results. This could also be due to the machinenot being re-calibrated like it should have been and therefore measured the wrongtension. The percent difference between the measured and calculated accelerationvalues was large. Measuring the acceleration was difficult and the values could beincorrect because the slope values I obtained for acceleration were inaccurate. Lab Manual Questions1. Force Diagrams (attached)2. The tension in the string is equal to mass two multiplied by gravity. The firsttension is going to be less than the tension in equation five because the frictionalforce in equation five is acting in the opposite direction of the motion of the cart,therefore increasing the overall tension. 3. Distance vs. Time and Velocity vs. Time (attached)Data
