Pd 6 quiz on Newton's First Law
Today, we'll first learn about how to draw free body diagrams in order to represent the external forces on an object/system. First read the PowerPoint below. Then watch the video below. Then practice on Free Body Diagrams Worksheet.
Presentation: Free Body Diagrams Powerpoint
Handout: Free Body Diagrams Worksheet
Homework: Draw free body diagrams for the objects on Free Body Diagrams Worksheet.
Video: This video was made for students in AT Physics, so there are some advanced concepts like knowing the direction of acceleration and also picking the "right" sign convention. There are also things about knowing if the forces equal each other that you can ignore for now. Just focus on how to draw the arrows and label them appropriately.
Today, we'll work on the following sections β Positive Physics unit 5: introductions to forces:
free-body diagram drawing 1
free-body diagram drawing 2
free-body diagram analysis 1
free-body diagram analysis 2
Note: The following abbreviations are used in β Positive Physics:
W - weight, aka force of gravity
N - normal force
Th - thrust
D - drag, aka force of air friction
A - applied force
Homework: Finish β Positive Physics unit 5 problems by Wednesday at 10pm. Only completion score will count, so you can continue to try if you get it wrong the first time. Try to finish these problems early in case you run into technical difficulty. No late credit.
Today we'll review the video from homework last night on Newton's Second Law through interactive lecture. We'll learn how to use our free-body diagrams to solve problems using Newton's Second Law.
In addition, we'll talk about the results of the lab and learn about what the accepted value is for our constant.
