Lab 05 – Gravitation and Keplers LawsName: _Sabrina Maxwell____Why everyone in this class is attracted to everyone else.Adapted from Chris Bier’s Collisions PhET Lab OPTION A: CREATIVE COMMONS - ATTRIBUTIONIntroduction:Every object around you is attracted to you. In fact, every object in the galaxy isattracted to every other object in the galaxy. Newton postulated and Cavendishconfirmed that all objects with mass are attracted to all other objects with mass by a forcethat is proportional to their masses and inversely proportional to the square of thedistance between the objects' centers. This relationship became Newton's Law ofUniversal Gravitation. In this simulation, you will look at two massive objects and theirgravitational force between them to observe G, the constant of universal gravity thatCavendish investigated.Important Formulas:221dmmGFProcedure: 1.Take some time and familiarize yourself with the simulation. Notice how forces change as mass changes and as distance changes.2.Fill out the chart below for the two objects at various distances.3.Rearranging the equation for Force, you can CALCULATE the value of G using the values given below for m1, m2, and d, and the value for the Force that you obtain in the simulation. Record the force between the two object and then solve (calculate G) for the universal gravitation constant, G and compare it to values published in books, online, or your text book. The numbers you calculate for G will vary slightly from row torow. Remember significant digits!15 pts I’m using distance to determine sigfigs.
