Abstract

The invention discloses a gravitational acceleration measuring instrument used for teaching. The gravitational acceleration measuring instrument comprises a roll ball and further comprises a protective tube. A spiral channel is formed inside the protective tube, and openings in the two ends of the spiral channel are formed in the upper end face and the lower end face of the protective tube respectively. The bore diameter of the spiral channel is larger than the diameter of the roll ball. The gravitational acceleration measuring instrument used for teaching has the advantages that the spiral channel is provided, the long channel can be obtained in the measuring instrument small in size, the size is small, measuring precision is high, and the measuring instrument can stimulate thirst for knowledge of a student.

Description

technical field [0001] The invention relates to a teaching instrument, more precisely a gravity acceleration measuring instrument for teaching. Background technique [0002] The acceleration can be calculated by measuring the distance and time that the ball passes through the inclined plane, and then the calculation of the acceleration of gravity is an experiment with strong interest, simple principle, convenient operation, easy to use, and low equipment cost. Through this Experiments can improve students' curiosity about science and technology and stimulate their desire for knowledge. However, this teaching instrument in the prior art needs a larger inclined plane to complete the experiment, which has high cost, low interest, and low measurement accuracy, and cannot better stimulate students' desire for knowledge. Contents of the invention [0003] The present invention mainly solves the technical problems existing in the prior art, thereby providing a spiral channel, wh...
