1. Use the velocity components to determine the direction of the velocity vector. Is it in the expected direction? 1. From the x-t and y-t images, the two curves show a sine and cosine relationship, indicating that the object is in uniform circular motion. Since position over time behaves as a sine and cosine function, this means that the velocity is their derivative, and the direction of the velocity is always perpendicular to the direction of the radius, so the velocity vector varies in the tangential direction, which is consistent with the theory of circular motion. The formula used to calculate speed 2. Analyze enough different points in the same video to make a graph of the speed of a point as a function of distance from the axis of rotation. What quantity does the slope of this graph represent? In this experiment, we investigated the relationship between radius, linear velocity and acceleration in uniform circular motion by analyzing the motion of three different points on a r...

Second Project

 In our group, it was just me, Venessa, so both Vanessa and I had a very heavy workload. Venessa used 3D printing to create the parts of the car and recorded video of the car moving and differentiated between the video and the physical modeling programmed into the computer. I built the physical model and used the conservation of energy and Newton's second law to come up with formulas for the linear acceleration and maximum speed and used these to create a program to simulate our car. The final slides were made by me and Vanessa.

Graph of experiments and calculations Data from experiments  formula was used to calculate the height Calculation uncertainty Where do the two curves match?   From the graphs of the data, it can be seen that when the central mass M<0.09, the experimental data are in good agreement with the theoretical curve ( predicted equation). Where do the two curves start to diverge from one another?   When M > 0.1 kg, the experimentally measured vertical displacement is significantly larger than the theoretically predicted value. What does this tell you about the system?  Show that the theoretical model (assuming no friction and no elasticity) is only applicable to the small mass case and that the actual system has pulley friction or rope elasticity effects. What are the limitations on the accuracy of your measurements and analysis? There is an uncertainty of ±0.005 m in the height measurement. (This was obtained by me and my team by measuring the same mass and t...
