π’ 6: W* 3/10, π΅ 8: Th 3/11 Hooke's Law
Today, weβll investigate how springs behave and learn about Hookeβs Law through an exploratory lab. In the lab, youβll try to answer the following questions:
Is the force that a spring applies constant?
If so, what is the force for a given spring? If not, how does the force change?
Is there energy associated with a spring? In other words, can a spring do work?
If so, how can you calculate the work done by a spring?
You will do a guided investigation using the π€ Gizmos "Determining a Spring Constant". Complete the worksheet during your investigation in βοΈ Google Classroom. Then answer the assessment questions at the bottom of the π€ Gizmos simulation.
Homework: Finish this π€ Gizmos in βοΈ Google Classroom before next class.
π© 6: Th 3/11, π¦ 8: F 3/12 elastic potential energy
π© 6: Th 3/11, π¦ 8: F 3/12 elastic potential energy
Today, we'll review what we've learned about Hooke's Law and elastic potential energy by doing problems from β Positive Physics unit 17: springs & oscillations "work" problems from the following sections (only 5 problems):
Hooke's law
spring energy problems
Homework: Finish these problems by Sunday at 10pm. Only completion score counts. No late work will be accepted. Quiz Monday on β Positive Physics units 13 (work & energy).
If for some reason you missed class today or you need a review, check out the following videos from Dan Fullerton:
Watch examples during time 7:45-11:05 only, unless you want more practice with other conservation of energy problems.
Finally, here's a more complex example like what you'd see on a test. (Think about how you'd do this with our Before & After diagram and our conservation of energy equation. Remember that the spring force is a conservative force.)
πβ 6: M 3/15, πβ 8: M 3/15 power
πβ 6: M 3/15, πβ 8: M 3/15 power
Quiz Today on β Positive Physics units 13 (work & energy).
After the quiz today, we'll finish our unit on energy by defining power as the energy per time. After giving a couple of examples, we'll do β Positive Physics unit 13: energy "work" problems from the section:
power problems
