We have check-boxes for System Centered, Show Traces, Show Grid and Tape Measure. Check against Measuring Tape check-box. Drag the Planet Mass slider towards 1. Hover the mouse on the bodies. Screen is provided with Initial Settings at the bottom. Point to red coloured arrow. See Related Materials for a link to the simulation and to a 10-minute video on gravity by the same author.

Let us begin our demonstration with Model screen. Slide Number 23 Acknowledgements This project is partially funded by Pandit Madan Mohan Malaviya National Mission on Teachers and Teaching. Here, star's mass is 333 thousand Earth masses and planet's mass is 1 Earth mass. Screen has a system drop-down box on the right side. Students will make predictions and tackle conceptual questions before attempting any mathematics. Size of the orbit also becomes small.

Here sun is not at the center of the orbit. With this orbit simulator, the user can set initial positions, velocities, and masses of 2, 3, or 4 bodies, and then see them orbit each other. Title Phet Solar System Simulation Lab:. This is the interface of My Solar System simulation. As you drag, observe the increase in size of the star. Click on drop down arrow and scroll down.

Point to the moon in orbit. Click on Start button and observe the orbits. Slide Number 12 Universal Law of Gravitation Universal law of gravitation- Force of attraction between any two objects is proportional to the product of their masses. Point to Gravity and Orbits simulation. After a few revolutions the comet collides with the Sun and disappears. Click on To Scale screen. It has four solar system like models.

Slide Number 19 Summary Identified the variables that affect the strength of gravity. Change the Initial settings and observe the changes in the orbits and Explain the observation. A planet orbits a sun in a perfect circle. Point to To Scale screen. Place cursor on Sun, Planet and comet. Notice that, Earth revolves around the sun along a circular path.

The interface has two screens. Next we will see what happens to earth in the absence of gravity. Then click on pause button. Lets measure the distance between star and Earth. Notice that, Direction of Earth's velocity is perpendicular to Sun's Gravitational pull. Point to drop down box. Here moon is a satellite of the earth.

We cannot offer interpretations about citations as this is an automated procedure. Earth will return to its default position. Simulations are often useful in modeling events and processes. Assume the velocity is increased when the planet is directly to the right of the sun. Now select Sun, Earth and Moon system. This screen has two additional check-boxes- Mass and Measuring Tape Click on Mass, Path and Grid check-boxes.

Slide Number 13 Universal Law of Gravitation This force is along the line joining the centers of two objects. This is the interface of Gravity and Orbits simulation. Point to 91503 thousand miles. Explain how gravity controls the motion of our solar system. Slide Number 8 Gravitational Force There exists a force of attraction between the Sun and the celestial objects.

Please note that this resource requires Flash, or Java Applet Plug-in. For any given object, a larger force causes a larger change in motion. Drag Planet Mass slider towards 1. This force acts towards the center. Sketch the new orbit if the velocity of the planet was suddenly increased by 25%. Click on Mass, Path and Grid check-boxes. Point to the Gravity force.
