ACCELERATION DUE TO GRAVITY LAB REPORT DISCUSSION FREE

The first step was solving for the equation for acceleration using free body diagrams and analysis of forces acting on the cart while it was on the inclined plane. In this lab, our group solved for the acceleration due to gravity on an inclined plane. The motion of a freely falling objects is one dimensional motion with constant acceleration. The direction of g is downwards, towards Earth’s center and it’s magnitude is approximately 9.81 sm2. Introduction Throughout this world, it is very well known that if the effects of air resistance are ignored, any object dropped near Earth’s surface will move with a constant acceleration g. Our resulting value for gravity was g = 10.0 sm2 This value was surprising due to the possible reasons for error which should have decreased the value for gravity.

We measured the acceleration of an object moving down an inclined plane using Logger Pro motion detectors. In this lab we found the local acceleration due to gravity g by measuring the acceleration of a cart on an inclined ramp at a specific angle. Henry Zhang Advanced Physics October 1, 2018Ībstract The rationale behind this lab was to find the relationship that the force of gravity had on a cart on an inclined plane. Instead of the acceleration being 9.81 m/s^2 as I hypothesized, it was actually 6.73 m/s^2 when calculated due to calculation and experimental errors.Local Acceleration Due to Gravity Lab Report My hypothesis was only partially correct. I concluded that the velocity-time graph did go in a straight line. A random error that occurred was that one group member released the object, not in synchronization with the ticker timer which may have hindered the process of dots being recorded on the tape. The anticipated error was that the numbers would have been rounded and not completely accurate.Īnother systematic error is that the ruler is not 100% accurate when measuring it may be off by. One error might be in the calculations in Table 1. ErrorsĪfter performing the experiment, several errors were noted. We know that velocity changes with t = time and displacement changes with v = velocity. Given the formula vf = vi +at and d = (vf +vi/2). Due to a change in velocity, there was a change in displacement. This was because as time increases, velocity changed at a constant rate.

The change in velocity of an object in free fall was directly proportional to the displacement. The velocity position graph (refer to graph 2) was curved because changing velocity means change in slope.ĥ. The slope of the velocity time graph was accelerating 6.74 m/s^2. The relationship between the change in velocity and elapsed time was that the velocity increases constantly as the time increases therefore they were proportionate.ģ. It was heading in a positive direction (refer to graph 1).Ģ. The velocity-time graph is in a straight line, meaning it was going at a constant acceleration. Therefore the acceleration throughout was 6.74 m/s^2 this may be caused by experimental errors and calculation errors.ġ. = 674 cm/s^2 (*note: To convert into meters, I divided (674 cm/s^2) by 100) Therefore at 0.2s, the average velocity was 92cm/s.Īcceleration was found by finding the slope of the velocity time graph. To find average velocity I did the following: One example calculation would be at 0.2 seconds, when displacement is 9.2cm. Position from the start (cm)Īverage velocity was found by dividing change in time by displacement. I measured and recorded the position from the start of the tape corresponding to each half time interval and then plotted a velocity-position graph using the velocities I recorded. I calculated the slope of the velocity-time graph, which gave me acceleration in cm/s^2.
