# ONLINE REMOTE CURRICULUM

GETTING STARTED

- calculate the force of gravitational attraction between the Earth and its's moon. Use values for your reference packet as needed. Write your response on a blank sheet of paper, being sure to show all your work including equation used, substitution with units, and final answer with units.
**Photograph your work and email directly to me.**

MONDAY 3/16/2020

- WKSHT: Calculate the centripetal force acting on the moon as it orbits the Earth.
**Photograph your work and email directly to me** - NOTES: Double this, 4 questions as notes)
- LAB: Centripetal motion in horizontal circle (lab directions) (virtual lab to accompany PDF)
- Use the virtual lab which represents swinging a rubber stopper around in a horizontal circle, balanced by a handing weight below it. You can change the weight of the hanging weight by clicking them to add more washers, you can adjust the radius of the rope, and you can adjust the mass of the rubber stopper using the arrow.
- Play around with the variables and see how changing each on impacts the speed of rotation.
- To do the lab, reset back to default values. You will let the stopper swing for 10 rotations and record the time. Repeat two times. Then fill out the lab.
- On a separate sheet of paper include the data table filled in and the mass of hanging weights below it. Then number and show work for the rest of the problems. Re-draw the six blank graphs at the end and draw in the line/curve as appropriate.

- So... check out this video clip, just the first 25 seconds or so...
- See, in the game you can uses "stasis" which locks an object in place.
- Link then hits the object several times with his sword, applying a force for some time (giving the log impulse)
- However, the log is "locked" and cannot move... once the "stasis" effect wears off then all impulse is resolved (the object's momentum changes)
- Another way to look at is is "Link stored potential energy in the log", then when the "stasis" effect wears off the stored PE is transformed into KE.
- https://www.youtube.com/watch?v=68KypFUu1gM

**email me your answers however you can**) - Play around with this online applet that demonstrates Ohm's Law... email me the answer to the following two questions below - (access applet here)
- What happens to the current flow (I) as you increase the voltage applied (V)?
- What happens to the current flow (I) as you increase the resistance of the wire conductor (R)?
- Please
**write an email back answering the above two questions.** - The two concepts shown about Ohm's law are always true, they will never fail you, and will always be helpful when analysing circuits. Commit the results to memory!

WEDNESDAY 5/20/2020

- I am putting together a virtual lab hopefully that you can work through on Thursday.
- Watch this short video clip from Youtube talking about amps (youtube link)
- Look over 4 example problems from notes here (https://drive.google.com/file/d/1iK-_1JD8eTLtorHcfhbsrCdKQQUaFhew/view?usp=sharing|notes PDF)
- Ohm's law is the fundamental relationship between voltage, current, and resistance
- Ohm's law is given in the reference packet at I = V/R
- The amount of current that flows depends on voltage applied to the circuit and the resistance of the circuit
- Many people like to write Ohm's law in one line like this: V=IR. This works if you don't like fractions... however this is not a 'functional' definition... when written this way, it looks like if you increase I or R then you get more V voltage... that is NOT true. The voltage is determined by the generator or battery supply... so keep that in mind!

- Watch this video clip showing a demonstration of Ohm's law (youtube clip)
- Look over the example note on Ohm's law (notes PDF)
- Optional, if you are having a hard time using Ohm's law to solve equations you can watch this 7 minute youtube video that goes over some more example problems using Ohm's law (youtube link)
