Abstract

The invention provides a circular motion acceleration integrated demonstration instrument. The circular motion acceleration integrated demonstration instrument comprises a rotational drive device. A rotatable disk is installed above the rotational drive device. Arc demonstration tubes are installed circumferentially on the rotatable disk, which are used to display the tangential acceleration. Radial demonstration tubes are also installed radially on the rotatable disk, which are used to display the radial acceleration. Several arc tube moving balls are arranged inside the arc demonstration tubes, and several radial tube moving balls are arranged inside the radial demonstration tubes. The circular motion acceleration integrated demonstration instrument is able to vividly, intuitively and separately demonstrate the normal acceleration and tangential acceleration, so that students can better understand the accelerations of the circular motion.

Description

technical field [0001] The invention relates to the field of circular motion teaching demonstration equipment, in particular to a circular motion acceleration comprehensive demonstration instrument. Background technique [0002] The normal acceleration and tangential acceleration in circular motion are affected by many parameters such as steering, rotational speed, and radius of rotation. There are positive and negative accelerations in tangential acceleration, which are related to the direction of rotation and the increase and decrease of angular velocity. Both normal and tangential acceleration are proportional to the radius of rotation. The normal acceleration is related to the angular velocity, and the tangential acceleration is related to the angular acceleration. The existing demonstration device used to demonstrate the acceleration of circular motion is generally a ball moving in a circular motion around a point. By observing the trajectory of the circular motion of...
