Function
1. Used to compare the speed of object movement experiments, explore the relationship between the speed of trolley movement and factors such as tension, friction surface, trolley mass, and the number of trolley wheels.
2. With the photoelectric gate sensor, the movement speed of the trolley can be measured, and the data can be presented in real time on Windows, Android, and iOS system terminals.
3. The trolley weight fixing rod can fix multiple weights of different masses at the same time, and can be matched with more than 10 combinations of different trolley masses without affecting the normal operation of the photoelectric gate, and explore the impact of different masses on the movement of the trolley.
4. The pull rod at the tail of the trolley can complete the switch between 4 wheels and 6 wheels in one step without changing the mass of the trolley, and explore the impact of different numbers of wheels on the movement of the trolley.
5. Adding weights of different masses to the weight barrel can provide more than 10 different pulling forces to explore the impact of different pulling forces on movement.
6. The friction between the pulley and the wheel axle is extremely small, which can effectively reduce the impact of axle friction on the experiment.
7. The blade-type wheel design has low friction with the track.
8. There is a spring shock absorber between the wheel and the car body to effectively protect the wheels of the trolley.
9. The guide rail fixing clamp can quickly fix or replace the track.
10. The guide rail profile comes with an 800mm scale, the photoelectric gate bracket can be moved freely and there is a red arrow mark on the side, which can clearly indicate the movement distance of the trolley.
11. Equipped with special experimental software, preset templates, automatic recording of single measurements, automatic calculation of average values for multiple measurements, and automatic recording of data changes in a table form, the experimental results are more intuitive and obvious.
Experiments
Experiments on the speed of the trolley movement, the average speed of the measured object, etc.
