Question description

I did a lab for my physics class and now I need help with the worksheet. I have attached the worksheet questions. 

Name Date Class Lab 17: Satellite Motion Purpose Satellite Motion To investigate the conditions for launching a satellite and maintaining stable orbital motion Background Try looking into the night sky in an open field away from city lights. If you look closely enough, you might eventually see what looks like a star moving quickly across the sky. But what you see is not a star. It is one of many satellites that have been launched into orbit around Earth. These satellites move around Earth in much the same way as the moon does. Satellites are carefully put into orbit and their orbit is maintained with just the force of gravity, but other orbiting spacecraft require booster rockets to maintain or change their orbits. The gravitational laws that govern orbiting satellites are simple, but require precise conditions to exactly reach the anticipated elliptical orbits. Skills Focus Predicting, controlling variables, drawing conclusions, observing cause and effect Procedure 1. Start Virtual Physics and select Satellite Motion from the list of assignments. The lab will open in the Mechanics laboratory. 2. The laboratory will be set up with a ball on the screen. The ball’s mass is 100 kg. Attached to the ball is a plunger that you will use to launch the ball into motion. A radial gravitational field, which is the same as Earth’s, has also been set up. You will hit the ball with the plunger and observe its motion as it is pulled by gravity towards Earth’s surface. The goal is to hit the ball with the amount of force that will put it into a stable orbit around the gravity center. 3. The ball is set 100 km away from the center of the radial gravity source. Predicting What will happen if you let the ball go without applying any force from the plunger? ISBN 1-269-73240-4 4. Try your prediction by clicking the Start button. The plunger is not hitting the ball at all. Observe the motion of the ball. The experiment will stop automatically when the ball reaches the source. 5. Click the Reset button to bring the ball back to the starting position. This time you will use the plunger to hit the ball. Use the Forces tab under the Parameters Palette to choose a plunger force. Remember that you want to put the ball into an orbit around the gravitational source. Start the ball by clicking the Force button. The experiment will stop automatically if the ball runs into the origin. Observe whether or not the ball goes into orbit. Satellite Motion 55 Virtual Physics Lab Workbook, by Brian F.

Reset the experiment and adjust the force if necessary using the Force section of the Parameters Palette. Record in the table below the force used, the reaction of the ball to that force, and what you think needs to be adjusted to reach a stable orbit. 7. Repeat Step 6 until you have found a force that makes the ball travel in an orbit around the source. Remember to Reset the ball after every attempt.

What other variables would affect the orbit of a satellite? Hint: Think about the variables the lab had already set, those that you didn’t get to choose. 9. Controlling Variables Reset the experiment and change one of the variables you just identified in Step 8, either by clicking on the ball and plunger or adjusting variables in the Parameters Palette. Using the same force you used earlier to achieve a successful orbit, launch the ball into orbit. What did you observe? Why? Satellite Motion Virtual Physics Lab Workbook, by Brian F.

ISBN 1-269-73240-4 56 Name Date Class Analyze and Conclude Satellite Motion 1. Drawing Conclusions Now you have learned about a few of the variables that NASA engineers think about when they put a satellite into orbit. The mass of the satellite, the orbit’s distance from Earth, and the amount of force in the direction of the orbit (thrust) are important variables for orbital motion. You will now adjust satellite motion with a rocket thruster force. Click on the plunger and drag it to the spotlight on the transfer table at the top of the screen. Click the green Zoom Out button, then click inside the Stockroom window to enter. Double click on the plunger to return it to the shelf, then double click the rocket to select it. Click the green Return to Lab arrow and click on the on-screen table or TV screen to return to the Experiment View. 2. Pull the rocket down and place it on the ball. Click the Force button to fire the rocket. It will only fire for 1 second. Adjust the ignition time, force, and angle until you can make a stable circular orbit. Report the conditions you chose. 3. Observing Cause and Effect You can also fire the rocket multiple times while the rocket is moving. Set up an orbit, then fire the rocket at different points of the orbit and record how the ability to add force at different times during the orbit affects the orbit. ISBN 1-269-73240-4 4. Set up an elliptical orbit and then fire the rocket when needed to transform the orbit into a circular orbit. Report on the positions in the orbit where it was best to fire the rocket in order to adjust the orbit. Satellite Motion 57 Virtual Physics Lab Workbook, by Brian F.

Super fast turn around time. Very impressed and will use Studypool again if I need a quick job. Communication was a bit tough but not unbearable.
