Unit 1 Quiz#2

Interpretting Graphs:

Consider the position vs. time graph below. The motion of five different people (A, B, C, D, and E) are shown on the graph. Study the graph and answer the following questions. Some questions may have more than or less than one answer.

Question:

  1. Which person(s) is/are moving with constant velocity?
  2. Which person(s) is/are moving in the positive direction?
  3. Which person(s) has/have a negative acceleration?
  4. Which person(s) change direction during the course of motion?

Mathematical Analysis of Graphs:

The graph below represents an object's motion for twenty seconds. Use the graph to answer questions 1 - 5.

  1. Use the graph to calculate the acceleration of the object at 6 seconds. PSYW

     

  2. Use the graph to calculate the displacement of the car during the first 8 seconds. PSYW

     

  3. Use the graph to calculate the displacement of the object from 8 to 16 seconds. PSYW

     

  4. Use the graph to calculate the displacement of the object during the entire 20 second interval. PSYW

     

  5. Use complete sentences and the language of physics to describe the motion of the object during the entire 20 seconds. (Do a "bang-up" job.)
