The mathematic analysis of a physical movement problem
Dong Guan-wen · Journal of Science of Teachers' College and University · 2012
Based on a physical problem analysis,reveals the laws of mathematics in the problem.Firstly,by the problem scenarios established the physical model,analysized the forces that effect the particle under constraint condition of the problem,proved that the motion trajectory of the particle is an ellipse.And then proved that the angle between the string ends and vertical direction are same,so the cord pulling force equal at both ends,and calculated approximation of the circumference of ellipse.It has a certain reference value for the mathematical and physical education in the future.
