Question

How closely does the measured normal acceleration (from the accelerometer) compare to the normal acceleration calculated from the potentiometer measurements.

Answer 1

Accelerometere An accelerometer is device that measure proper acceleration proper acceleration, being the acceleration of a body at its own instaneous rest frame is not the same as coordinate acelerations being the coordina in the fireed the acceleration in a fixed coordinate system Ex An accelerometen at rest on the surface of the earth will meascon an acceleration due to earth gravity straight upwards of g = 9 diants By constant, acceleration accelerometer is free ball (falling toward the centre of the earth at the rate about 9181 m/82) will measure zeso.. so accelerometer measure normal acularahon is actual +9.81mig? in the upward direction: Potentiometer & - A potentiometer is a three terminal resester with a sliding or rotating contact that forms an adup table voltage devider ef only two terminals are used one end and the wipe it act as variable resister or rheostal It is used to measure electric potential. From than the above defenitions we compare to potentiometer got for Accelerometer is better acceleration measurement. Teacher's Signature
