My Solar System

Identity Period

Introduction: Every physics pupil has had a whole lot of experience with the force of the law of gravity. Unfortunately, this experience is limited to the interaction between an extremely large target, the Earth, and far smaller things that are very close to this. This is an extremely limited variety of the possibilities. Computer software simulations of gravity let physics students to explore various other gravitational interactions among objects. These types of activities are created to be used with the JAVA applet My Solar-system that can be found on the Physics Education Technology (PhET) website at the University of Colorado for Boulder. Directions: Go to the My own Solar System ruse on the PhET website and carefully stick to the instructions for each and every activity. Answer the concerns and record your benefits before going onto the next activity. The simulation can be found at this URL: http://phet.colorado.edu/sims/my-solar-system/my-solar-system.swf Activity one particular: Look over the start screen. The simulations settings and configurations are on the ideal and simulation inputs have reached the bottom. Select Start to see the results in the middle and lower right. The paths in the objects in the simulation are displayed along with past time. Just click Stop and move the cursor over each target. Its current position and velocity will be displayed beneath the time. Simply click Start once again and note down at least 2 findings about this simulation below.

Activity 2: Click on the Show Grid box and make sure that Program Centered and have absolutely Traces are checked as well. Drag the slider pub all the way to the left for the most accuracy. Just click Reset, in that case change Body system 1's mass to five-hundred and its times and sumado a position and velocity to 0. Modify Body 2's mass to 30, it is x placement to 200, and sumado a position and x and y velocity to zero. Reset should always be visited before changing position and velocity of the current simulation. Write down the prediction intended for the action of both equally Bodies beneath before clicking on Start to understand. Body 1 (Yellow) movement:

Body a couple of (Purple) motion:

Q1: Were your predictions correct? How many range units will one sq of the main grid represent? Simply click and fatigue the lower correct corner of the window to create it 15 grids large.

Q2: Alter Body 2's mass to 0. 001. Click Start again. What is different regarding the result? So why do you think this really is?

Q3: What should be the course of Body 2's initial velocity in order that it doesn't ever before hit Physique 1?

Q4: Increase Human body 2's con velocity by increments of 10 until it doesn't contact Body 1 ) At what velocity performs this first happen? What is the form of the ensuing orbit?

Q5: Continue to enhance Body 2's velocity before the orbit contains a circular shape. Using the main grid, adjust that by increments of 1 until it is as close to a perfect group of friends as you can get. What speed resulted in a circle? Is the speed of Body a couple of constant? End it since it crosses the grid within the opposite side and place the cursor over the top of it to validate.

Q6: May be the velocity of Body a couple of constant? Explain.

Activity three or more: Draw a free-body picture of Body system 2 in the circular orbit below. Using Newton's Second Law, legislation of Gravity, and the equation for centripetal acceleration, obtain an expression pertaining to the General Gravitational Constant, G. Using the values through the simulation, solve for the importance of G utilized in the simulation. Show Your entire work below. Verify your result with the teacher before going on.

G =

Q7: Make use of your formula from above to derive an equation pertaining to the speed associated with an object in a circular orbit. Using this equation and your benefit for G, solve for the speed necessary for a third body to be within a circular orbit with a radius of 100. Show your entire work and your final solution below.

Activity 4: Change the quantity of bodies to 3. Notice that the positioning and speed for Body system 1 and Body a couple of changed as you clicked by 3. Alter them backside, then arranged Body 3's mass to 0. 001, its times position to 100, its y speed to your worth...
