Gravity Simulator Learning Goals: SWBAT Review the direction of the forces acting for a satellite orbiting a large body Review the direction of the velocity of a satellite orbiting a large body Review what happens to a satellite if you remove its tangential or orbital velocity Note: Remove the lines to type answers and use a different color to highlight your work. Open Internet Explorer and enter the following into a Google search: phet gravity and orbits Clicking on the first result should bring you to http://phet.colorado.edu/en/simulation/gravity-and-orbits Click on the green button RUN NOW! Play with the simulator for 5 minutes, trying out different settings. You can pause and move the Earth and/or sun. You can also change the velocity of the Earth. Click on the velocity vector button. You can click and drag the tip of the velocity vector. Make 5 observations about what you see happen on the simulator as you play around with different settings. _______________________________________________________________________ _______________________________________________________________________ _______________________________________________________________________ _______________________________________________________________________ _______________________________________________________________________
