Gravity Lab - Space Simulator for Android

11 things about Gravity Lab - Space Simulator

1. Gravity Lab includes a short 4-page guide explaining the Newton's law of universal gravitation, the first two of the three Kepler's laws of planetary motion and the concept of gravity assist in spaceflight.

2. According to Newton's law of universal gravitation, every massive body in the universe influences every other massive body, and it works exactly the same in Gravity Lab.

3. By being gravitationally attracted to a rock weighing more than 13,000,000,000,000,000,000,000,000 lbs (or almost 6,000,000,000,000,000,000,000 metric tons), we are not very good at intuitively understanding the universal effects of the gravitational forces.

4. Gravity lab is a perfect aid for anyone seeking a deeper understanding of physics, or just willing to play around with their own simulated universe.

5. Gravity Lab is a great tool to explore the laws of nature that govern everything in the universe.

6. It allows you to create dozens of particles with different masses and different initial velocities by simply tapping the screen or drawing a velocity vector.

7. You can toggle a switch to show the acceleration vectors of the bodies, which are proportional to the forces between the bodies and inversely proportional to their masses.

8. All these concepts can be demonstrated using Gravity Lab.

9. Gravity Lab is a gravity simulator for iPad.

10. The positions and velocities of all the particles are recalculated in real time.

11. For us, standing here on Earth, gravitational forces always point down.
