Configuration:
Electromagnet, photogate sensor (0 ~ ∞s), aluminum bracket, base, storage box, light barrier *3 (1.4cm, 1.6cm, 2.0cm), hook weight *2 (10g, 20g), USB power adapter, data cable, Bluetooth adapter
Functions & Applications:
1. Used in "free fall motion" experiment, it can verify that free fall motion is uniformly accelerated motion, and the change of mass does not affect gravity acceleration, and the value of gravity acceleration can be calculated.
2. Setup is easy. By releasing the light barrier for free fall movement, the photogate sensor can measure the falling speed without external sensor and datalogger, and the data can be presented in real time on Windows, Android and iOS system terminals.
3. Electromagnet release design, release the light barrier through the electromagnet switch, can make the it free fall, no need to hold by hand, effectively reduce the release of human factors on the initial state of the light barrier.
4. Provide hook weights with 2 kinds of mass and light barriers with 3 different grating widths, which can be combined with 6 kinds of combinations to explore the influence of mass size on gravitational acceleration when the object is moving in free fall and explore the influence of different light barrier on gravitational acceleration.
5. Equipped with special software, the velocity of the falling process can be traced to fit, and the slope of the fitted curve can be read to directly obtain the measured gravitational acceleration value.
6. With energy-saving mode, no operation for 10 minutes, automatic shutdown.
