Option B: Collision Scientific Investigation
Before you begin the scientific investigation below, make sure to download the One Dimension Collisions Scientific Investigation Report. As you complete this scientific investigation, fill in any needed information on the report template. If you need more information about each section of the report, please visit the Developmental Module.
This scientific investigation is available below or in a printable version.
Interactions other than explosions are generally categorized as collisions. Elasticity is a measure of the amount of kinetic energy that is conserved after the collision. Normally, when objects bounce off of each other some kinetic energy is lost. In special cases, the kinetic energy is conserved. When they bounce, they are usually somewhat inelastic, and in special cases, they are perfectly elastic.
Objectives
In this scientific investigation, you will:
Hypothesis
Using the Procedure and Data Collection section below, read through the procedural information for this scientific investigation. Based on your understanding of the procedure, develop your own hypothesis which describes your expected results. What is the relationship between mass, velocity, and momentum? Record these hypotheses in the Hypothesis section of your One Dimension Collisions Scientific Investigation Report.

Mass, Velocity and Collision
Data Analysis
In the Data Analysis section of your One Dimension Collisions Scientific Investigation Report, provide responses to the following questions:
Effect of Mass In One Dimension Collision
Effect of Velocity In One Dimension Collision
Conclusion
Using the Conclusion section of your One Dimension Collision Scientific Investigation Report, compose three to four sentences describing an overall conclusion about one dimension collision based on your data. Were your hypotheses true or false, and how do you know? Use the data and notes that you collected from your simulation experience to form your conclusion. Make sure that you include information that you gained from data analysis to support your conclusion.
Experimental Sources of Error
On your One Dimension Collisions Scientific Investigation Report, provide responses to the following questions: Are there any sources of error? If so, what are they and what could be done to minimize error?
