Go to http://phet.colorado.edu/simulations/sims.php?sim=My_Solar_System and click on Run Now.
1. Move the slider all the way to accurate, click on the tape measure and the grid.
2. Click the radio button for 4 objects and run the simulation until the purple planet (body 2) has made one complete orbit (one year).
3. After the first orbit (year), turn off the traces (show traces box) and watch another orbit (year) of the purple planet (body 2).
Question One:
Is blue moon (body 3) circling the yellow sun (body 1) or the purple planet (body 2)? Explain your answer.
Using the trojan asteroids setting it looks like all 3 bodys are orbiting the yellow sun
4. Increase the mass of the sun (body 1) to 400 and allow the simulation to run

Why?
When the mass of the sun is 1000 and the planet is 10. Because the mass of the sun is 10x larger than the planet.
Question Five:
What makes the length of the year increase and decrease? Why?
The closer to the sun a planet is the shorter the year and the farther away it is the longer the year.
Question Six:
A planet in a circular orbit would always be the same distance from the sun. What do you notice about orbits with the shortest years? Why? Shorter year = closer to the sun. The closer it is to the sun the more of a pull the gravity has on it which causes it to orbit quicker.
8. Choose the ellipses preset from the pull-down menu.
9.You may move the slider bar about 2/3 of the way towards fast for this simulation.
10. Run the simulation until the green planet (body 4) returns to its starting point (one planetary year)
Planet Time of One Orbit (planetary year) Closest Distance to Sun (perihelion) Farthest Distance to Sun (aphelion)
Purple Planet (body 2) 2.2s 54 84
Blue Planet (body 3) 7.6s 54 250
Green Planet (body 4) 14.7s 54 419
11. Change the y velocity of the blue planet (body 3) to 90 and the green planet (body 4) to 70.
12. Run the simulation again until the green
Instructions: Complete a five year simulation, and answer the following questions on the actual approach you used for the simulation. You may type your answers directly on this form, but the completed document must be 2-3 pages in length (please do not change the margins). Due November 25, 11:59pm
More sunlight reaches the equator of the planet causing a correlation between UV intensity and latitude.

First, obtain a SpectroVis Plus device and connect with its corresponding LabQuest2 device. You need to calibrate by turning on the machine, allow the inner lamp to start heating up, and prepping a blank in the process. Obtain a dry cuvette, fill it with distilled water, and place into the SpectroVis plus device. Before doing so, be sure to wipe the outside of the cuvette with a Kimwipe to clean off any fingerprints that might be present. Fingerprints will skew with the calibration. Once the device notifies you that calibration is complete, click okay and prep for the next part of the lab.
Set the radius to 2.0 m, the mass to 1.0 kg, and the velocity to 10.0 m/s.
First, The procedures of were take an energy car and roll it down a track with a without a sail and record the data from photogate A to B and the time to took to get there make sure the photogate are 555 cm away from each other. Do the same one energy car wit just wheels and one with one 3 times each.
Pluto, a dwarf planet, and Uranus, a planet, take turns being the most distant of the major bodies of our solar system in reference to the Sun For years, scientists were under the mistaken hypothesis that Pluto was the most distant. Scientists, in an attempt to study astronomical data, learned their hypothesis was inaccurate. Fortunately, it is of the scientists nature to investigate all data. On the basis of the data, the astronomers learned of the fact Uranus and Pluto have intersecting orbits. In addition, during the course of their investigation, they learned much of the nature of Uranus and Pluto.
Predict what will happen and run the simulator three times, recording your data for each run. Answer the following:
| 17. Which of the following statements regarding the motion of objects on the celestial sphere is true? Answer
a) Click on the reset button. Adjust the glider masses back to 0.5 kg. Reposition the gliders with G1 on the left end of the track, and G2 on the right end, since both gliders will have an initial velocity moving toward each other for the collision. The exact position of each is not important, as long as they can collide near the middle. b) Record the masses of G1 and G2 in Table D. Calculate and record the combined mass of the gliders as well. c) Set the velocities to 3.0 m/s for G1, and –3.0 m/s for G2. Record the initial velocity and momentum of each glider in Table D as well. d) Press play to run the trial. After the collision, press pause to record velocity and momentum data for the combined gliders in Table D. e) Run a second trial. Click the reset button and change the mass of G2 to 0.8, and keep the other parameters the same. Record masses, velocities, and momentums as you did in Steps 3b–c, this time in Table E. Run the simulation, pausing after the collision to record postcollision velocity and momentum of the gliders in Table E. f) Repeat Step 3e to run a third trial where the mass of G2 is increased to 1.2 kg. Record masses, velocities, and momentum both before and after the collision in Table F. Step 4: Compare values for momentum. a) In each Table, find the momentum for each glider prior to the collision and for the combined mass after the collision. Momentum is calculated by using the
Before the two colossal planets were formed into a pair, they each wandered the deepest darkest crevices of space in complete desolation, and relied on none other than themselves. Now, the pair will revolve around one another for all eternity, and completely rely on each other for their own survival; without one the other is unable to survive on their
The issues inherent in the simulation are not textbook problems or questions in which answers are cut and dried and determined quickly.
With each planet, you can rotate and zoom in on its three dimensional figure. While observing each planet individually, you are given a new fun fact about it. These fun facts are also available for the moons of each planet. In addition to the fun facts, each planet is
Purpose: The purpose of the practical is to find how mass affects acceleration and how it affects also the force of the accelerating body. To do this we are going to do the ticker tape experiment where an accelerating body pulls a tape through a consistent 50 dot per second ticker timer. The acceleration body in this experiment will be a small trolley pulled by a string that is pulled by the downfall of different masses which will then tell how mass affects acceleration.
