The Rotation Theorem of Rigid Body Plane Parallel Motion with Different Reference Axes—Taking Question 7 of the 33rd National High School Physics Competition Finals as an Example
The Rotation Theorem of Rigid Body Plane Parallel Motion with Different Reference Axes—Taking Question 7 of the 33rd National High School Physics Competition Finals as an Example
By deriving and summarizing the rotation theorem of rigid bodies with different reference axes through the angular momentum theorem of particle systems,the 7th question of the 33rd Physics Competition semi-finals is solved from different perspectives,in order to expand students'problem-solving ideas and methods,and provide reference for physics competition teaching.
