Gravity acceleration experimental instrument

The utility model belongs to the teaching is with acceleration of gravity experimental facilities field, and concretely relates to gravity acceleration experimental instrument includes the frame and set up beating in the frame and mark the device, mark the target, the frame on still be provided with the controller, the mark stick is hung in the frame with the help of the electro -magnet that sets up in the frame, the mark device of beating include motor drive's the parameter of beating, be provided with spring trigger mechanism on beating the periphery of parameter, with the help of the cooperation of beating the mark device and marking the target, realization measurement acceleration of gravity's mesh to through regulating spring trigger mechanism's elasticity, the realization spring force's that can also step forward experiment kills two birds with one stone, helps the student to understand and participates in the experimentation, cultural knowledge that help understanding was acquired. 本实用新型属于教学用重力加速度实验设备领
