Question

calculate the velocity with accurate information ​

Answer 1

Answer:

Explanation:

The small accuracy variation error may be due to the following:

i) Movement of the mobile phone/tablet accelerometer sensor are usually in 3 dimensional movements rather than along a single axis. Hence, trigonometrical errors will occur unless the mobile device has a large number of accelerometer sensors to measure miniature accelerations along various axes.

ii) To account for the various reference planes of the mobile phone/tablet movements, more than 1 accelerometer sensors will be needed to calculate accurate readings as at least 1 accelerometer sensor will be required for each plane.

iii) If the mobile devices is held on the hand, the hand's natural vibrations will introduce another small accuracy variation error to each acceleration reading.
