PHYS 1010 – page 9 x x Position Velocity Acceleration x Position Velocity Acceleration
Lab Assignment Sheet Verbal Representation: Initially I designed this experiment around the idea that acceleration would be constant as the cart rolled down the slope, similar to our previous lab. However, as seen by the data that is not what occurred. Instead, acceleration acted similarly to velocity, initially increasing then decreasing. Even though gravity is constant at 9.8 m/s 2 we know that on an inclined plane the normal force of an object will be less than the objects weight and as the angle of the incline plane is increased the speed at which the object moves will also increase. However, I failed to consider that when an object is traveling down an incline like a ramp that has a changing slope, the acceleration will change proportionally to the slope, which is exactly what happened. Therefore, this experiment became more complicated when trying to understand the mathematical representation. With that in consideration, If I were to continue the future, I would like to run 2 trials on different slopes that have different curvatures in incline and look more specifically at the rate of change in acceleration between the two. In regard to velocity, as predicted, immediately after the release of the IOLab cart velocity increased initially but then decreased while traveling down the incline. Additionally, I correctly predicted that the cart was unable to make it over the second incline. I believe that the length of the ramp and steepness in slope combined to prevent the IOLab to pick up enough speed for it to make it over the second incline. And as predicted the relationship between time and position resulted to be a positive relationship, as seen in graph 1. This physics that occurred within this experiment are comparable to a skateboarder skating down a half pipe at a skate park. In their situation, the skater is able to take off down the ramp, picking up enough speed as they go to be able to get up the other side. These situations are not identical, given that the skater is also able to control their speed and acceleration manually and gain enough momentum, none the less the concepts are very similar. In the future I would be curious to see if I were to increase the steepness of slope and make it longer, if the cart would have made it over the second incline. PHYS 1010 – page 10
