Kinematics Maxwell Mueller 1/21/2022 Activity 1: Graph and interpret motion data of a moving object
Activity 1. Table 1 Time (x axis) (seconds) Position (y axis) (meters) 0 0 5 20 10 40 15 50 20 55 30 60 35 70 40 70 45 70 50 55 Insert your graph here for Distance vs Time of a Moving Object. Questions for Activity 1 Question 1: What is the average speed of the train during the time interval from 0 s to 10 s? 4 m/s Question 2: Using the equation: v = s 2 s 1 t 2 t 1 , calculate the average speed of the train as it moves from position x = 50m to x = 60m. .66666 m/s Question 3: What does the slope of the line during each time interval represent? Acceleration Question 4: From time t = 35 s until t = 45 s, the train is located at the same position. What is slope of the line while the train is stationary? 0 Question 5: Calculate the average speed of the train as it moves from position x = 70m to x = 55m. What does the sign of the average velocity during this time interval represent? -3m/s, The negative average velocity means the train is moving toward it’s original position during that interval. Question 6: What is the displacement of the train from time t = 0s until t = 50s? 55 m Question 7: What is the total distance traveled by the train from time t = 0s until t = 50s?
85 m Question 8. What is the slope of the line during the time interval t = 45 to t = 50? -3 Question 9: What does the sign of the slope in question 8 represent in terms of the motion of the train? The negative sign means that the train is moving towards its original position. Question 10: What is the average velocity of the train during the interval t= 0s to t = 50s? 1.1 m/s Question 11: Does the train’s average velocity during the interval t= 0s to t = 50 s provide a complete picture of the train’s motion during this time? Looking at only the average velocity during this time would not account for the period in which was stationary or in which the train was moving back toward its original position. The average velocity for the interval is positive and that would. be misleading as to the actual motion of the train during this interval. Activity 2. Calculate the velocity of a moving object. Activity 2. Table 1 Time (s) Displacement (m)* 0 0.77 1.55 2.51 3.26 4.00 4.76 5.50 6.24 *Note that 0.25 m = 25 cm Insert a graph of Table 1 here. Include a chart title, axes titles and units.
