Objectives

        Analyze the relationship between velocity and acceleration

        Calculate an objectís average acceleration

        Collect data and interpret it

        Create and analyze a graph showing acceleration

 

A. Pre lab Questions

1.      What is acceleration?

 

 

 

 

 

2.      How does it relate to velocity?

 

 

 

 

 

 

B. Group Lab 1: Gone in 60 Seconds

 

You will work in pairs to calculate an objectís acceleration.We will watch a clip from the movie.Pay close attention to what is happening in the scene.Write down your observations.

 

1. Observations

 

 

 

 

 

 

 

 

2. In pairs. Based on the information available in the scene, work with your partner to write a procedure to determine the acceleration.

 

Procedure

 

 

 

 

 

 

 

 

C. Class Discussion. As a class we will decide on standard procedures to determine the acceleration.

 

Procedure

 

 

 

 

 

 

 

 

 

 

D. Data Collection

We will watch the clip.Record the data for column 1 and 2. Be sure to note the units.

E. Group Lab 2: Fast and Furious

 

You will use the procedures from Section C.

 

Observations

 

 

 

 

F. Data Collection

We will watch the clip.Record the data for column 1 and 2. Be sure to note the units.

F. Calculation

1.      In column 3 in Section D and F, write down the velocity in meters per second.To convert velocity from miles per hour to meters per second:

 

Velocity (miles/hour) X 1/3600 (hour/seconds) X 1609 (meters/miles) = Velocity (meters/second)

 

 

 

2.      Look in your book to find the formula for acceleration.Record this calculation in column 4.

 


Analyzing the Results

 

Graph velocity on the y-axis and time on the x-axis
