Exploriments: Newton's Law of Universal Gravitation
Detailed App Info:
Application Description
We have created an imaginary meter that calculates and displays the gravitational force so you don’t have to figure it out each time. We’re debuting a new format for our educational content - a Guide that is subdivided into Map, Explore and Discovery to let you feel a pioneer’s excitement. Also for the first time, you can directly post your thoughts about an activity straight to Twitter, Facebook or Google+. Share thoughts, build your community, start a revolution.
Exploriments are virtual, interactive, simulation-based experiments that use engaging and insightful explorations to facilitate conceptual learning. Visit www.exploriments.com to know more.
Activities:
Exploring Newton’s Law of Universal Gravitation
--- Understand the relationship of gravitational force to distance.
--- Experience the change in gravitational force by changing mass.
--- Explore the inverse square law to get further insights into Newton’s Law of Gravitation.
Firing Newton’s Orbital Cannon
--- Learn the importance of the launch velocity in achieving orbit.
--- Appreciate the scale of Newton’s thought experiment through this virtual implementation.
--- Get an introductory insight into the types of orbit.
Putting a Satellite into Orbit
--- Vary the launch velocity as well as the launch altitude to understand their roles in achieving orbit.
--- Verify the launch velocity needed for circular orbit at different launch altitudes.
--- Study the variation in velocity of a satellite in elliptical orbit.
Studying the Effect of Altitude on 'g'
--- Vary the altitude of a satellite and observe the change in 'g'.
--- Learn to distinguish between distance and altitude.
--- Learn to compare and contrast graphs, by studying two graphs that involve 'g'.
Deducing the Radius and Mass of a Planet by Varying the Altitude of a Satellite
--- Learn to relate the weight of an object at various altitudes to planet radius.
--- Experimentally determine the radius of a planet.
--- Use theory to calculate the mass of a planet from the experimentally determined radius, then compare it to official values.
Additional Features:
--- Highly interactive simulation
--- A Reset button to reload the activity with diverse values to learn better through practice.
--- Imaginary meter to help visualize an invisible force.
--- Social interaction enabled - Twitter, Facebook and Google+
