[0002] In ordinary physics teaching, gravitational acceleration is the acceleration of an object under the action of gravity. In physics teaching, the measurement of gravitational acceleration is often involved. At present, the methods for testing gravitational acceleration include single pendulum method and chute method , Dot timer measurement method and drip method, etc. Among them, the chute method can only measure one set of data in one experiment, and then take the average value after multiple sets of measurements, and the parameter data test is inconvenient, time-consuming and laborious; in addition , to verify the relationship between the magnitude of friction, the degree of surface roughness, and the magnitude of gravity is also an experiment often involved in physics teaching. At present, the equipment designed for this experiment is mostly fixed, with poor adjustment, and it is also a single-group single-time experiment; in view of Therefore, the present invention combines the experiment of verifying the relationship between the magnitude of friction, the degree of surface roughness, and the magnitude of gravity with the measurement experiment of the object's acceleration of gravity to provide a physical kinematics experiment teaching demonstration model
