AP Physics 1 Investigation 2: Newton`s Second Law
... Newton’s laws are the basis of classical mechanics and enable us to make quantitative predictions of the dynamics of large-scale (macroscopic) objects. These laws, clearly stated in Isaac Newton’s Principia over 300 years ago, explain how forces arising from the interaction of two objects affect the ...

4 Newton’s Second Law Experiment 4.1
... In this experiment a low friction air track will be used to test the validity of Newton’s Second Law. A hanging mass will be attached to a glider placed on the air track by means of a light (negligible mass) string. By varying the amount of mass that is hanging we will vary the net force acting on t ...
