Module 3—Effects of Force on Velocity
Module 3: Lesson 1 Assignment
Remember to submit the answers to LAB 1, LAB 2, and LAB 3 to your teacher as part of your Module 3: Lesson 1 Assignment.
Lesson 1 Lab: Relating Acceleration and Net Force
With the approval and supervision of your teacher, go to pages 144 and 145 of your textbook and complete “3-5 Inquiry Lab: Relating Acceleration and Net Force.” This lab is best done in groups of three or four students, if possible.
LAB 1. Write a hypothesis. Follow the directions under the subheading “Hypothesis” on page 144 of your textbook.
LAB 2. Complete all the steps of “Procedure.” Then answer questions 1, 2, 3, 4, and 5 of the “Analysis.” You will create copies of “Table 3.2” and “Table 3.3” on page 145 and submit the tables with your recorded data to your teacher.
LAB 3. Answer questions 7, 8, 9, and 10 of “Analysis” on page 145 of your textbook.
In “3-5 Inquiry Lab,” you kept the total mass constant (controlled variable) and changed the net force (manipulated variable). What would happen if you kept net force constant and manipulated the total mass? Complete the lab titled “Relating Acceleration and Mass” to find out.
