OLD Honors Physics 21-22-4A Assignments

Do these problems on your own sheet of paper.

ATTEMPT the last two problems. You'll need to remember Newton's 1st law to solve these. The sum of forces on an object is 0 if not accelerating (static = motionless). Also, you'll need to remember Newton's 3rd law. If A pushes/pulls on B then B pushes/pulls on A with an equal force in the opposite direction.

Use this simulation to study Coulomb's law. Don't forget to log in!

Goal: How do each of these variables: charge size and distance affect the force of attraction/repulsion between charges?

Procedure: 
1. Once you're in the simulation, check the box at the top for show distance and the 4 boxes at the bottom.
2. Set up the charges however you want to start. 
3. Change only 1 variable at a time: Charge 1 OR Charge 2 OR distance. Keep the others the same and write their values down for future reference.
4. Record at least 8 "trials" for each variable. That means you'll end up with 3 graphs with at least 8 points each. When you record the force, record the value in the absolute value bars at the very bottom. 
5. Graph your data and if any graphs are not linear, linearize them.
6. Describe the relationship between each variable and thef orce between charges. 

Use the "Lab" in this link to determine the spring constant of 2 different springs and then determine the mass of the unknown masses. 

Record yourself and your partner(s) throwing a projectile. Make sure the whole path is included in the video and there is something in the video that you know the size of (You, a meter stick, a desk, etc.)


Draw a sketch of the motion of your projectile. Include the observations and calculations required in this list below. Turn this assignment in on paper.

Watch your video in slow motion and/or frame by frame. 
Record the range and height (make sure to include initial height if it didn't start at the ground.
Record the time that the projectile is in the air (to the best of your ability)
Using that collected data, calculate the launch velocity with angle. 

This is a paper assignment in class. Complete this on your own paper if you are absent/remote.

Go to the Gizmos webpage and use the Force and Fan Carts Gizmo. Follow the instructions in the attached Form.

Click all the checkboxes except for speed. Set the friction however you'd like.

Experiment 1:
Choose 1 mass for your system (box, person, water cup, a combination, etc.). Record this value for later.
Set the applied force to 10 different forces that cause the sum of forces to not equal 0 N. Record the acceleration of the system with each force.
Plot this data with Sum of Forces on the x axis and acceleration on the y axis.

Experiment 2:
Choose a sum of forces that you'll be using for each trial. Record this for later.
Set the mass of the system to 10 different masses by combining the various items/people. Apply the sum of force that you chose and record the acceleration for each trial.
Plot this data with mass on the x axis and acceleration on the y axis.





Once your data is collected, linearize any curved data, and analyze your results. Write a CER to answer the question: What is the mathematical relationship between acceleration and net force as well as acceleration and mass?


Remember...
C - Claim. -The answer to your question(s)
E - Evidence - Data tables, graphs, research, etc. collected.
R - Reasoning - Explain how your collected evidence lead you to your answer. This can include scientific principles that we've already learned about, mathematical reasoning, etc.

Take the practice test and check your answers (It will grade itself when you submit).



You'll have time to work on this in class if you want it, but you can start on this anytime.

Use the link attached here to view and manipulate the simulation. 
Complete the questions on the handout in class. 
When you're done with the worksheet, complete the "quiz" to test your understanding. 
Ask questions in class as you get stuck and/or leave comments here on the assignment.

Write your answers on a separate sheet of paper. We'll discuss this on Thursday.

This will be completed in class, but you can complete this at home if you miss class.
