It did not take longer the first time, the actor just reacted late when he clicked the stopwatch. The second time, he was more prepared, and pushed the button sooner.
Hello! I was just wondering if I could use your video for our physics project? It's a short video about Atwood's Machine, where we explain why objects of equal masses, when attached to each other and set up on this machine will not move and why, if any force acts upon it for an instant, the masses will move at constant speed. We need this video for comparison. Can we use it?
The Atwood machine is used to study moving kinetics and dynamics, eg. Newtons second law (F=mg). By varying weights and timing the movement. Perhaps the cool thing about it is the low friction bearing on the top. A difference of a few grams makes it move. Though this one here looks a bit deformed.
You can apply Newton's Second law to determine the acceleration of the system and from that, you can determine how much time it should have taken to hit the ground. This "theoretical" value can be compared to an average experimental value.

I love how the lab coat is not necessary at all

This is science, dammit! Of course it's necessary!

Interesting, but how efficient can this be? Got any numbers?

The value of g I calculated from this demonstration is 9.555 m/s^2 or 2.6 % error from the reference value of g. Not too bad .

that guy isn't timing it correctly.

Wow! My calculations are giving 4.86 s. That's 1.34% error from the averages of the two time values. :)

I will credit you for it (naturally). ^_^

nice reaction time

there was a slight percent error in the timing, but very little so can be considered negligible if doing a demonstration

@ramanturbz Whys this been thumbed up? Theres a percent error in everything, congrats for pointing that out?

@9hello123 There is no percent of error when I refuse to observe! SCIENCE=BLASPHEMY YOU ALL WILL BURN AT THE STAKE!!!!!

In theory, it should take about 4.76 s for the heavier mass to hit the ground. Cool stuff.

Pretty good, considering the average was 4.80. He has a reaction time error of only 0.04s
