I have some answers for the first page, but need help with the rest of the first page and with the second page!
Name: Abbey Lovelace Why everyone in this class is attracted to everyone else. 0 Adapted from Chris Bier's Collisions ATTRIBUTION Lab PTION A: CREATIVE COMMONS - Introduction: Every object around you is attracted to you. In fact, every object in the galaxy is attracted to every other object in the galaxy. Newton postulated and Cavendish confirmed that all objects with mass are attracted to all other objects with mass by a force that is proportional to their masses and inversely proportional to the square of the distance between the objects' centers. This relationship became Newton's Law of Universal Gravitation. In this simulation, you will look at two massive objects and their gravitational force between them to observe G, the constant of universal gravity that Cavendish investigated. Gravity Force Lab Important Formulas: ,,-Gm1m21 E=ma at Procedure: https://phet.Colorado.edu/en/simulation/gravity-force-lab L L *Take some time and familiarize yourself with the simulation. Notice how forces change as mass changes and as distance changes. Fill out the chart below for the two objects at various distances. 1. 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 vou obtain in the simulation. Record the force between the two obiect 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 to row. Remember significant digits and units!!!!

Answer Herel Average value of G Published value of G Units of G: Source How did your average value of G compare to the published value for G that you found? Answer Herel Page 1 of 2Explanation / Answer
Average value G = 6.6 X 10-11 SI Unit newton square meter/ square kilogram
Predicted value of G = 6.67 X 10-11newton square meter/square kilogram.
1.Gravitational force is always attractive.
2. Gravitational force is equal on both lighter and massive body.
3.Distance between masses is measured from their centres.
4. Distance between masses decrease force increase.
5.If mass of each object is doubled force between them becomes 4x.
6. If the distance is halved and one mass is doubled force becomes 8x.
7. Mass of central object.
