2. Exploring the momentum theorem
3. Verify the law of conservation of mechanical energy
4. Exploring the relationship between work and energy
5. Measuring instantaneous speed
Instructions:
Connect the photoelectric gate sensor to the intelligent acquisition terminal with the data line. There is no power-on button and zero-key button, and then the software can be directly collected by opening the software. The photoelectric gate sensor is a continuous optical path formed by using high-precision photosensitive devices, and can block the light blocking of the object. Time, under the condition that the light blocking width of the moving object is known, the light blocking time of the object is recorded, and the moving speed of the object can be obtained. If two photogate sensors are used at the same time, not only can each photogate block time be measured, but also the time when the moving object runs between the two photogates can be obtained. When using two photogates, the order of the photogates must be judged first. And to ensure that the height of the photoelectric door allows the light blocking film to block the photoelectric door.
