Today, we'll use class time to finalize ideas for the forensic physics activity. Last time, you should have come up with an idea for how you will design the model. In your group today, you'll be collaboratively creating what you think will be the best mathematical model that the police could use to investigate car crashes. Today, you will populate the following sections of the lab in β©οΈ Pivot Interactives.

• Pre-lab preparation

• Constructing the mathematical model

Only groups who have completed this section will be able to take data next class! If you do not take data next class, you will have to take data on your own time outside of class!

Homework: Make sure your Constructing the Mathematical Model section of the "Forensic Physics" lab in β©οΈ Pivot Interactives is totally complete by next class, or you will not be able to take data. Momentum Assessment on Tuesday, March 22nd!

Today, having already created a mathematical model of the car crash, you will use a physical model to take data for the Forensic Physics Lab. Your goal today is to populate the following section of the "Forensic Physics" lab in β©οΈ Pivot Interactives. You will have one more day to work on this.

• Designing and performing the experiment

You'll take your lab data and do your final analysis. You need to run trials with different conditions. You should ultimately have a graph with three or four data points. Linearize the graph if necessary. How do you extract the coefficient of kinetic friction from the best fit line? You should not be finding the coefficient using particular data points and averaging! That is not the way we do science!

Homework: If you have not completed testing your mathematical model with a physical model, then make sure you have a really good plan to do this at the beginning of next period. Momentum Assessment on Tuesday, March 22th!

Today, having already created a mathematical model of the car crash, you will use a physical model to take data for the Forensic Physics Lab. Your goal today is to finish populating the following section of the "Forensic Physics" lab in β©οΈ Pivot Interactives.

• Designing and performing the experiment

You'll take your lab data and do your final analysis. You need to run trials with different conditions. You should ultimately have a graph with three or four data points. How do you extract the coefficient of kinetic friction from the best fit line? You should not be finding the coefficient using particular data points and averaging! That is not the way we do science!

Then you will design a second experiment to verify the results of your physical model. You may use a method that we've used in a previous lab.

Homework: If you have not completed testing your mathematical model with a physical model, then make sure you have a really good plan to do this at the beginning of next period. Momentum Assessment next class - Tuesday, March 22th!
