Introduction
• A data logger (also datalogger or data recorder) is an electronic device that records data over time or in relation to location either with a built in instrument or sensor or via external instruments and sensors. Increasingly, but not entirely, they are based on a digital processor (or computer). They generally are small, battery powered, portable, and equipped with a microprocessor, internal memory for data storage, and sensors.

Carrying out the experimentTitle : Acceleration-Cart on an inclined track with different angle
Objective• Investigate how acceleration of object depends on the
angle of the inclined tract by using the motion sensor
• Determine the angle of the inclined track for each different height, h
• Use the software to plot the graph of position, velocity, and acceleration versus time for each trial.

Set-up of equipment and apparatus
![Page 12: Powerpoint presentation for data logging](https://reader036.fdocuments.us/reader036/viewer/2022062405/5561af24d8b42ae9708b5404/html5/thumbnails/12.jpg)
Procedure
Computer setup• The PASPORT USB interface is plugged into the
computer’s USB port.• The motion sensor is plugged in into the USB
interface. The PASPortal window is automatically launched.
• Appropriate DataStudio configuration is chosen.
![Page 13: Powerpoint presentation for data logging](https://reader036.fdocuments.us/reader036/viewer/2022062405/5561af24d8b42ae9708b5404/html5/thumbnails/13.jpg)
Equipment setup• The equipment is set up as shown in figure.• The height of the point of release of the cart from
table surface is measured. Different heights (8cm, 12cm and 16cm) are used in this experiment. The length of the track is also measured to obtain the inclined angle.
Height, h
Length of track, l

• The motion sensor is placed at the raised end of the track so it can measure the motion of the cart as it moves down the inclined track. At the top of the motion sensor, the icon ‘Cart’ is selected.
• Cart is hold at the mark “15cm” of the track. When it is released, the data is recorded. The experiment is repeated by changing the height to 12cm and 16 cm to obtain 3 sets of data.
![Page 15: Powerpoint presentation for data logging](https://reader036.fdocuments.us/reader036/viewer/2022062405/5561af24d8b42ae9708b5404/html5/thumbnails/15.jpg)
Record Data • The button Start is
clicked and the cart is released so that it moves down the track.• The button Stop is clicked
before the cart hits the end stop of the track.

Analyze data Velocity graph• The smooth part of the velocity is highlighted. Then,
linear fit is selected from the fit menu. The slope (the value of m) for the cart is then recorded.
Acceleration graph• The flat part of the acceleration is highlighted. Then,
linear fit is selected from the fit menu. The slope (the value of m) for the cart is then recorded.
• The value for the slope of the velocity to the mean of acceleration is compared.

-mg sin θ increase
-mg cos θ decrease.
-Acceleration and velocity increase.

without wasting more
time
The changes of the data and graph can be observed immediately, allowing students to make any changes or
detect and overcome any errors in the experiment.
The experiment can be repeated many times to obtained the accurate readings

Conclusion
Each of these experiments was very quick and easy to set up. Using the simplest mode of operation of the software means that almost no knowledge or experience of data logging is required.
