I recorded a video of the experiment:
Our air track is exactly 2 meter long. Since there are bumpers at the ends of the track and the glider itself is 13 cm long, the total distance traveled is slightly less than 2 meters. It's a little hard to see in the video, but the front of the glider is at the 20-cm (or .20-m) mark on the air track. The audible click occurs when the front of the glider reaches a position of 2.00 m.
- How far does the glider travel as it slides down the ramp in this experiment?
- How long does the trip take? (HINT: use a stopwatch while viewing the video or, depending on your browser or software, use the video's time code.)
- The glider starts from rest and accelerates constantly during its trip. What is the value of this acceleration?
If you do these calculations, please briefly explain how you are getting your results. How does our "hand" calculated value for the glider's acceleration compare to both the theoretical value and the computer-measured value?
Yes, the acceleration of the glider can be determined without a computer by simple hand calculation. Although the calculation may not be 100% accurate, it can still be measured.
ReplyDeletei really liked how you added a video into the blog. it made it easier to understand!
ReplyDeleteawesome video
ReplyDelete2. i think the trip lasted around 3 seconds.
Yay! My acting debut is a success! Now, let's try to quantitatively answer questions 1 through 3... ...
ReplyDelete1. I'd say the glider moves about 1.5 meters down the ramp. That's just an estimate because I don't have an accuarte meter stick there mesuring it.
ReplyDelete2. The trip lasted around 4 seconds.
sciencegeek101, that's a good start; however, all the measurements you need are right in the paragraph right below the video. What you can't really see is that there is a measuring tape affixed to the side of the air track.
ReplyDeleteYou can determine the acceleration without using a computer. It wont be 100% accurate, but it will be close.
ReplyDeleteSnickers, you're right. Can *you* do the calculation?
ReplyDeletefor question number two the glider lasted about 3-4 seconds.
ReplyDeletei think the glider moves about 1.8m because it is starting at the.20m mark and the track is 2.00m long. i think the trip takes 2-3 seconds. i'm not sure about the acceleration...maybe .6 m/s2. the computers value would be more accurate.
ReplyDeletewell for the distance traveled i read what was given. the air tract itself is 2.00 meters and the glider itself is 13cm so u convert centimeters into meters (.13) then find the difference n thatd be 1.87m traveled.
ReplyDeletefor number two i used a stopwatch, started from the moment after one and then stopped jus a milisecond before it hit the end avoiding human error. n i got 2.25s it took til it hit the other end. so where u guys got 4s i have no idea its kinda out of the neigborhood.
haha anonymous that's hilarious. I really want to comment on something new, but he hasn't posted anything. :/. & nice work caluculating the distance and time!! seems about right!
ReplyDeletethanks man i just put my mind to it and look wat i got the right answer! lol but we shouldnt rely on yale physics to do all the dirty work wat else could we answer? the last question now how do we find the value people?
ReplyDeleteThanks for the comments this week!
