Hi Physics Forums,
I have two sensors that I am trying to relate:
- One gyroscopes measuring angle
- Two accelerometer measuring linear speed
I have put the gyroscope in the middle of a long rectangular tube. While the accelerometers are at each end of this tube.
I need help getting started...
Given that I have the footage. I have found a software called Tracker (http://physlets.org/tracker/), which is free. It allows to track the movement of an object and like NascentOxygen mentioned, it will plot the time vs position of each plot. I have not finished yet but it has been a big help...
You make a good point, Merlin3189. So from a video footage, there's no way of obtaining the maximum velocity... at least nothing I can think of. It would just be the average speed. I do have the footage to watch.
The simple pendulum equation of v = √2g * L * (1-cos(a)) would not be an accurate...
I used the energy formula to get an approximation of what the value should be (roughly) given that its larger than a small angle approximation. That was from v = √2g * L * (1-cos(a)) where g=9.81, L=0.51m, a= 90deg
But in the second equation, I get 4.738 km/hr for the velocity. which is half...
Homework Statement
Video was recorded with a 240 fps camera. It took 93 frames for the pendulum to go from 90 deg to the bottom. The pendulum length is 51 cm.
Homework Equations
Find the max velocity
The Attempt at a Solution
From the simple pendulum equation, I should get around 11.36 km/hr...
