Plausibility Arguments and Universal Gravitation
Cunha, Ricardo F. F.; Tort, A. C.
Physics Education, v52 n3 Article 035001 May 2017
Newton's law of universal gravitation underpins our understanding of the dynamics of the Solar System and of a good portion of the observable universe. Generally, in the classroom or in textbooks, the law is presented initially in a qualitative way and at some point during the exposition its mathematical formulation is written on the blackboard and some quantitative consequences are discussed. In the present paper we argue that this approach can be improved by the use of plausibility arguments.
