PRE-LAB PREPARATION SHEET FOR LAB 2: CHANGING MOTION (Due at the beginning of Lab 2) Directions: Read over Lab 2 and then answer the following questions about the procedures. 1. In Activity 1-1, how do you expect that your position-time graph will differ from those you observed in Lab 1, where you were moving with a constant velocity? 2. Show how you would add the two vectors shown below: + OBIECTIVE 3. Show below how you would subtract the second vector from the first. 4. In words, write down definitions for average velocity and instantaneous velocity. OV 5. What do you predict the direction (sign) of acceleration will be for the ex- periment in Activity 3-2: Speeding Up Toward the Motion Detector?
The Correct Answer and Explanation is:
