Newton's Laws
This unit bundles student expectations that address the analysis of force and motion using Newton’s laws and free-body diagrams. Students develop an understanding of Newton’s three laws of motion, the knowledge of force vectors, and visualizing forces using free-body diagrams. These diagrams provide powerful tools for analyzing motion. Students explore key dynamics variables including torque, force, mass, and acceleration, as well as the relationship between these variables. The relationship will be explored conceptually, graphically, and with equations.
ASSIGNMENT: Mass v. Weight
1. Watch the video above.
2. Find 5 objects in this room and record their mass on Earth in a table.
3. Then, calculate their weight here on Earth.
4. Finally, record their mass and calculate their weight on the moon. Hint: your table should have 5 columns and 6 rows.
5. Write 3-5 sentences summarizing what you've learned.
1) Watch the video introducing gravity and acceleration in free fall on the left.
2) If a feather and a hammer were dropped in a vacuum, which would hit the ground first? Discuss your answer to this question with me.
3) See me for a copy of free fall practice problems. Use the video no the right for an example and a collection of formulas you may choose to use on the problems.
ASSIGNMENT:
1. Take a paper and divide it in thirds. At the very top of the paper, write "Newton's Laws of Motion". At the top of one section, write "Newton's First Law". At the top of the next section, write "Newton's Second Law". At the top of the third section, write "Newton's Third Law".
2. Watch the video on Newton's Laws and fill in your notes.
3. Take notes on each of Newton's Laws. See me for a card sort of scenarios with Newton's Laws.
4. Use your new knowledge to take a short quiz on the link above (on the right) and see if you understood Newton's Laws. If you don't do well on the quiz, see me so we can review.
ASSIGNMENT:
1. Visit the website above on using Newton's Laws to solve problems.
2. Read the instructions on how to solve problems using Newton's Laws.
3. Then, solve the problems on your own paper following the steps suggested by the instructions.
4. Show me the process you are using by solving one problem next to me.
ASSIGNMENT: Open the virtual lab link above.
1. Get a copy of the data table you will need to complete during the lab from me.
2. Follow the directions on the left side of the screen to complete the virtual lab and fill in your data table.
3. Then, open the journal icon on the left bottom of screen and answer the journal questions on your paper using complete sentences.
ASSIGNMENT: Watch the video on constructing and interpreting free body diagrams.
1. Create a bubble map on Free Body Diagrams.
2. Open the link on the right above to explore different forces that effect motion of an object.
3. Then, make up your own scenario and write a description of the forces acting on an object of your choice. Draw the free body diagram of your object. Your scenario must include at least 3 forces acting on the object.
ASSIGNMENT:
1. Complete the assignment above on force and free body diagrams. See me for a copy.
2. Show me your work and explain how you solve this type of problem. Write a 3-5 sentence summary on how to solve this type of problem.
ASSIGNMENT:
1. Watch the video on torque.
2. Create a bubble map on torque.
3. Then, complete the project posted below.
ASSIGNMENT:
1. Use the sites above to check your understanding of the content in this unit.
2. Get any wrong and have a question? Let me know and we can work it out!
3. Be sure that you aren't just throwing numbers in to a calculator. SHOW YOUR WORK.
You are ready for your unit exam! Extra time? Easy peasy? See me about watching about "The Dark side of Newton".
