The goals of Lab #3 Part 1 are to learn how to graph, calculate, and describe changes in motion, as well as witness first-hand the relationship between acceleration, velocity, time, and the physical environment. We will be using numerous tools and devices, including a ramp, a small cart, a launcher, and a motion detector. We will use these tools to simulate motion and collect data about the simulation. The data will be recorded in a computer program, and we will. use this data to analyze acceleration and velocity by applying the data to various graphs, formulas, and principles. Using the data that we collected, we found that the acceleration from average slope was 0.45± 0.0481 m/s 2 The goals of Lab #3 Part 2 are to learn to describe and calculate gravitational acceleration. and velocity, as well as witness first-hand the relationship between gravity and the material/diameter of the ball. We will be using three different materials for the balls: metal, wood, and rubber. Each trial will consist of dropping a given ball and using a photogate and computer software to record the data of each trial. Using the data, we will calculate the velocity. of each drop and will compare our results to the rest of the class. We calculated that g for the metal ball was 25.695 m/s 2 , g for the wooden ball was 14.063 m/s , and that g for the rubber ball 2 2 was 2.857 m/s 2 . The average value of g from the three balls was 14.205 m/s 2

The goals of Lab #3 Part 3 are to learn how density, radius, viscosity, distance, time, and gravitational acceleration are all related to each other. We will be dropping nylon balls with different diameters into liquids, and then we will use that data to calculate and analyze viscosity. We will then graph our data to help us further visualize and understand the relationship all of the factors have with one another. We found that the average time t that the 0.15875 cm radius ball took to reach the bottom of the bottle for its first trial was 134.32 s. The 0.1984375 cm radius ball had a t of 122.80 s. The 0.238125 cm radius ball had a t of 81.44 s. The 0.3175 cm radius ball had a t of 48.43 s. The 0.47625 cm radius ball had a t of 19.85 s. The t for the 0.15875 cmradius ball's second trial was 152.76 s. Introduction The main goal and purpose of this lab is to be able to understand how changes within an object's mass can affect its time traveled, velocity, acceleration and momentum. While doing this experiment, I realized that the more mass an object has, the faster an object travels while going downhill and the object will have a greater acceleration. Overall, throughout the experiment we had to be able to get a final result for the variable "g", which stands for gravity. At our latitude on earth, gravity is measured at 9.80 m/s 2 . Our group had a result of 9.33 m/s 2 with an uncertainty of ±1.5 and overall, the class average for g was 9.108 m/s with an uncertainty of ±1.729
