Projectile Motion

ANGRY BIRDS

LAB JOURNAL

ACTIVITY

PART A. VIDEO ANALYSIS

PART B. CALCULATIONS

1. Write down the information gathered from the graphs for the Horizontal and Vertical components:

v_ox

v_oy

2. Calculate the magnitude and direction of the launch velocity v_o.

3. Calculate the total time the bird is in the air.

4. What is the maximum height achieved by the bird?

5. What horizontal distance does the bird travel?

OBJECTIVE

In this lab activity you will be uncovering

the basic principles of Projectile Motion

by analyzing the popular Angry Birds

game.

GRAPH ANALYSIS

PART I. LOGGER PRO

DIRECTIONS

1. Download the attached movie to the desktop

2. Open LoggerPro

3. Insert the Movie

4. Set the scale.

5. Mark the video

PART II. VIDEO ANALYSIS

DIRECTIONS

x-Component

Use the ANALYZE graph feature to do a LINEAR FIT

y-Component

Use the ANALYZE graph feature to do a CURVE FIT and select QUADRATIC

The equation is in the form:

X = AT²+BT+C

The meaning in kinematics language should be:

This is an example of an object falling. The values obtained are:

PART III. LAB JOURNAL

DIRECTIONS

1. Scale: describe the item used and the scale.

2. Sketch the position versus time graph for the x-component.

3. Write a qualitative description of the x-component motion shown on the graph.

4. What information was gathered from the Analyze feature? Write down the information obtained with appropriate units. (Hint: what does the slope represent?)

5. Sketch the position versus time graph for the y-component.

6. Write a qualitative description of the motion depicted on the graph.

7. Use the Analyze feature and write down the information obtained with appropriate units. (Hint: what equation describes this graph?)

8. Logger Pro graphs

a. Print a copy of the graph for you and your partner and paste it on your journal
