Introduction
The continuous evolution in the field of technology has rendered cellphones an indispensable component of education for student utilization especially in the field of physics. Cellphones have contributed massively in the facilitation of physics classes, research and significant experiments in data collection and processing through inbuilt sensors. These sensors include accelerometer, magnetometer, location sensors, gyroscope, and proximity sensors. Among ways in which these sensors make work easier, is the application of cellphone applications that are open-source to facilitate device performance of physics measurements such as acceleration. The acceleration sensors in cellphones have also been used in physics to perform experiments involving XXXXXXXXX XXX XXXXXXXXXX. For XXXXXXX, XXXXXXXXXXXX XXXX free XXX damped which XXX affected by the XXXXX’s XXXXXXXXXXXXX XXXXX (XXXXXXXXX XX al., XXXX)
XXXX Collection using Smartphone XXXXXXX
The XXXXX of XXXXXXX in cellphone XXXXXXX has XXXXXX up the XXXXXXXXXXX XX XXXXXXXXXXX XXXX XX XXXXX that involve data XXXXXXXXXX in XXXXXXX. XXXXX XXXXXXX include XXX gyroscope which senses angular velocity, the XXXXX XXXXXX, XXXXXXXXX XXXXXX, XXXXXXX XXXXX XXXXXX, XXXXXXXXX, accelerometer XXXXX XXXXXX force and even XXX XXXXX XXXX monitor. XX combination with XXXXXXXXXXXX in XXXXXXXXXXX, these XXX XX XXXXXXXXXX XXXX XXXXXX XXXXXX XXXX as play XXXXX and XXXXX store, theses XXXXXXX collect and XXXXXX XXXXX XXXX.
The Gyroscope
XXXX XX a motion-XXXXXXX XXXXXX XXXX is rotational. This measures rotation on a fixed XXXX. The smartphone XXXXXXXXX sensor is XXXXXXXX of a small XXXXXXXXXX mass XXXX XXXXXX XXXX the change in angular XXXXXXXX. These XXXXXXXXXX movements XXXXXXX XXXXXXXXXX XXXX current electric signals which are low. XXXXX, these XXXXXXX XXXXXXXXXXXXX and XXX read XX a host XXXXXXXXXXXXXXX. Data XXXXXXXX XX the XXXXXXXXX is XXXXXXXXXX in XXX/s. XXXXX XXXXXXX are XXXXXXXXX XXXXXXXXX XX dynamics in XXXXXXXXXXX. Poor quality gyroscopes can XXXXX up XX XXXXX changes XX XX XXX XX X.XXX rad/s.
XXXXXXXXXXX, the determination XX XXX axis XXX which rotation is being XXXXXXXX XX crucial. Since the gyroscope XXXXXX XX the smartphone XXXXXXX on XXXXXXXXX of all XXXXX fixed coordinated axes, XXXXXXXXXXX XX the parallel axis theorem is essential. This will facilitate drawing XXXXXXX XXXXXXX from XXX data XXXXXXXX XX XXX sensor (Usman &XXX; XXXXX, nd).
The XXXXXXXXXXXXX
XXXX XX a XXXXXXXXXX XXXXXX XXX linear XXXXXX. XXXXX XXX sensitive XX XXXX XXX gravitational XXXXX XXX linear acceleration. XXXX operates on XXX principle XX the XXXXXX XXX XX motion. It XXXXXXXXX a XXXXX XXXX XXXXXXXX to springs and with XXX freedom XX XXXX XXXXX in a XXXXXXXX. XXX application of a XXXXX XXXXXX XXX XXXXXXXXXXXXX to report the amount of XXXX XXXXX that XX ideal to sustain its XXXXX mass within XXX casing of this XXXXXX. XXX XXXXX mass of the XXXXXXXXXXXXX XX XXXXXXXXX through springs to a XXXX(substrate).
XXX up XXX XXXX XXXXXXXX XX the proof XXXX and fixed plated constructs XXXXXXXXXX. Since the XXXXXXXXX XXXXXXX XX reliant XX the base XXXXXXXX and geometrical change of the capacitor, a shift in distance between XXX XXXXXX XXXXXX about an XXXXXXXXXX signal. XXX detection of XXXX signal is directed to a conditional XXXXXXX XXX output reported ing.The difference with a triaxial XXXXXXXXXXXXX XX that the later XXX three sensors XXXX XXX XXX XXXXXXXXXXX and orthogonally oriented XX each XXXXX. Conventionally, XXXXXXXXXXXXX data is XXXXXXXX ing.

XXX reading XXXXXXXX from the accelerometer in a physics XXXXXXXXXX XX then XXXXXXXXXX XX X.XX for successive XXXXXXXXXX XX m/s2. XXXX XXXXX in a resting position XX a flat surface, XXX accelerometer XXXXXXX XXX following XXXXXX XXXXXXXXX XXX fixed XXXXXXXXXX XXXXXXX XXX smartphones:

Therefore, an accelerometer that XX in a XXXXXX working XXXXXXXXX XXXXXX XXXXXX the results XXXXX. XXXX XXXX XXXXXXX to its normal calibration.
Use XX Cellular Phone XXXXXXX in Damp Harmonic XXXXXXXXXXX.
Smartphone XXXXXXX can also XX used in physical XXXXXXXXXXX XXXXXXXXX damp harmonic XXXXXXX. In a given experiment to study damp harmonic XXXXXXXXXXXX, the XXXXXX XX XXX in an XXX track XXX reduced. The XXXXXX XXXXX shows the setup for XXX experiment (Monsoriu et XX.,2014).

XXXXXXXXXX
XXXXXXXXXX sensors XXXX XXXXXXXXXXXX demonstrated XXXXXXXXXXX in XXXXXXXXXXX experiments in XXXXXXX topics such as Mechanics. Various XXXXXXXXXXX have been made XXXXXX XXX XXXXXXX to perform XXXXX XXX applications of XXXXXXXXXX sensors XXXX XXXX massively utilized. Teaching concepts in physics XXXXX than XXX XXXXXXXXXX XX XXXXXXXXXXX have XXXXXX to XX XXXXXX with XXX use XX different smartphone XXXXXXX. XXXXXXXXXXX, cellphone sensors have XXXX XXXX XXXXXX for both XXXXXXXX XXX XXXXXXXX XX physics.
