Abstract

The kinetic impulse demonstrator is composed of a free body, a circular track, a dynamometer, a constant force regulator, a micro motor, a constant force fixed body and a pressure device. The constant force fixing body is the main body fixing part of the present invention, and the constant force fixing bodies are arranged symmetrically on both sides of the spherical track. A constant force regulator is arranged on the constant force fixed body, an annular track is arranged between the two constant force fixed bodies, a free body is arranged on the annular track, a micro motor is arranged at the center of the ring track, and the power output of the micro motor The end is connected with a pressure gauge. The two ends of the pressure device are provided with free bodies that can move on the circular track. Said free body is connected to said constant force regulator by chain cable, and the length of chain cable is adjusted by constant force regulator. A dynamometer is arranged on the chain cable to measure the force generated by the free body in the movement driven by the micro motor, so as to obtain the constant force value and calculate the impulse. The present invention has the advantages of simple overall structure, convenient operation and use, intuitive demonstration effect and accurate measurement data.

Description

Technical field: [0001] The invention relates to a physical experiment instrument, in particular to a kinetic impulse demonstrator. Background technique: [0002] A measure of the time-cumulative effect of a force, as a vector. If the force on the object is a constant force F with constant magnitude and direction, the impulse I is the product of F and the action time t. If the magnitude and direction of F are variable, the impulse I should be calculated by vector integral. Impulse is usually used to calculate the force between objects in a short period of time, such as the force of impact, that is, to estimate the force from the momentum increment of the object and the time of action. This force is also called momentum. The unit of impulse in the International System of Units is Newton·second. However, in the existing physical experiment equipment, there is no related equipment that can directly demonstrate the relationship between momentum and impulse. Invention conte...
