Kinematics Lab This lab explores objects moving with either a constant velocity or a constant acceleration and involves the use of graphs and equations to analyze the motion of that object. Preparation (5 minutes) Activity 1: Graph and interpret motion data of a moving object (15 minutes) Activity 2: Calculate the velocity of a moving object [20 minutes) Activity 3: Graph the motion of an object traveling under constant acceleration (20 minutes) Activity 4: Predict the time for a steel sphere to roll down an incline (10 minutes) Activity 5: Demonstrate that a sphere rolling down the incline is moving under constant acceleration (20 minutes Note: Additional time (one to two hours) will be needed to complete the lab report following the activities. Read through the overview, objectives, and background information provided in the Kinematics Investigation Manual. Review what materials will be needed (p. 8), the Safety procedures (p. 9), and acquire the needed materials that are not supplied. . Prepare for the activity by reading through the entire set of instructions prior to starting. The instructions are found on pages 1028. Set out all materials necessary for this activity that are listed in the Materials section (p. 8) in preparation to perform the activity. Make sure that you have set aside the necessary time to perform the activity. This is listed in the Time Requirements section (p. 3). Perform the activities, following the instructions carefully (p. 1128). Allow additional time (one to two hours) to complete the lab report and upload the lab report document when nished.
