HP Cycle 7

🟢 5: Th 10/12 - relationship between force, mass, and motion - planning & investigation

Today, we'll start a big lab for this marking period. We will design an experiment to determine the relationship between force, mass, and motion.  We will talk about how we would go about finding the relationship between THREE different variables.  

Then, we'll use 🎞️ Vernier Video Analysis to investigate the motion of a fan cart.   (Access licensed version of 🎞️ Vernier Video Analysis in ClassLink.)  A fan cart experiences a constant net external force.  By the end of this lesson, you should be able to describe the motion of a fan cart by looking at the position vs time and velocity vs time graphs of the cart.  

Directions: Once you're in 🎞️ Vernier Video Analysis, select to open the "Fan Cart" video from Sample Videos.  In the settings gear button, change "Advance Frames" to 5 frames.  Then advance the video to the frame where the fan cart is released.  Click the Add button on the left and then the Track button.  Place the crosshairs over a significant feature of the fan cart (maybe the yellow piece of tape), and then click "Start Auto-Tracking" at the top.  The app should record the position of the fan cart at different points in the video.  Click on the axis titles on the right graph to view the relevant motion, and determine with your group how you would describe the motion of the fan cart.  This is the first question in your lab for next time.

Homework:  If you have not finished the fan cart video analysis, do that in 🎞️ Vernier Video Analysis (access through ClassLink) by Friday's class.  

🟩❗  5: F 10/13 - relationship between force, mass, and motion - data collection

❗ Assessment on Newton's 1st Law TODAY!

Today, in ↩️ Pivot Interactives, you'll work on one of two labs (I will assign you only one):

• finding the relationship between force and acceleration with the lab called "Fan Cart: Force & Acceleration (Scaffolded) BCF."  

• finding the relationship between mass and acceleration with the lab called "Fan Cart: Mass & Acceleration (Scaffolded) BCF."  

It is very important that you finish your assigned lab by next class period so that you can exchange data with your partner lab group!!!

Homework:  Finish at least collecting data for your assigned ↩️ Pivot Interactives lab above by next class time!  Both ↩️ Pivot labs are due on Tuesday, October 17th at 10pm.  No late work will be accepted.

💚5: T 10/17 - finishing ↩️ Pivot Labs

Today is the last day we have to spend on the two labs in ↩️ Pivot Interactives.  They are due at 10pm TONIGHT!

You'll first share your data from the first lab with your partner group.  Then, you'll work through your understanding of linearizing any non-linear graphs.  Then finish both of the ↩️ Pivot lab write ups.  

On the worksheet I distributed in class (📄 LAB: N2L Pivot Lab findings & final equations), write down the equation you found for the mathematical relationship between force and acceleration for your particular fan cart mass.  Also, write down the equation you found for the mathematical relationship between mass and acceleration given a particular fan speed.  Don't forget that all numbers in your equation (slope & intercept) must have units.  Units are embedded inside variables, so you do not have to write units with variable letters.  Make sure your equations of each line do NOT contain x and y, but rather m, F, and a accordingly.  

Homework:  Make sure you've completed both labs by 10pm Tuesday, October 17th!  No late work will be accepted in Pivot.  Remember to complete 📄 LAB: N2L Pivot Lab findings & final equations.   ❗Lab quiz on Monday, October 23rd.
