#Goals: SWBAT...
1. set up a lab experiment without being given specific instructions. (think on your own, folks)
2. collect vx data
3. determine delta x correctly
4. get the ball bearing in the cup, 1st time
Warm-Up (5min)
- What is a "plumb bob"? (look it up if you need to)
- In which field of work is a plumb bob used?
- do you have anything in your possession that can function as a plumb bob?
***Warm-Up check this Friday - 2 weeks worth of warm-ups (Day 10-19). They should be labeled and organized***
CLASSWORK
1. #018A: Pre-Lab completion
- Work in your groups. Each person must write their answers on their own paper, which will be your "ticket" to begin the lab Thursday. If your pre-lab isn't complete and correct, you'll have to finish it instead of working on the lab with your groupmates....
- Your pass to get the materials is a completed pre-lab document, and you being able to answer the question, "How will you measure vx?"
- Here's the link to the pre-lab: LINK
2. #018B: lab data collection
- Make a data table with displacement and time. On your table, mark your xi and xf points with small pieces of tape - I suggest that your displacement length should be .50m, but it's up to you. You must collect constant velocity data on a FLAT SURFACE. Collect 10 trials for vx. Take the average of those ten vx values to find your average vx
- Find delta x for your projectile motion
- find delta y between the top of the cup and the table top (you can measure the ycup, ytabletop, and _________ the two.
- solve the free-fall problem to determine the time to fall delta y
- Use a plumb bob to find the initial x position for your projectile motion
- using the time you determined above, determine the x displacement (use a plumb bob to make the edge-of-table position on the floor).
- When you're ready, call me over for your one attempt, and put your cup in the correct spot. Video your attempt.
At Home Learning (HW)
Warm-up check tomorrow. Make sure day 10-18 are complete, organized, and labeled.
