COVID-19 TESTING Since the beginning of the pandemic, our team has done everything we can to get our nation back to normal. While still supporting those in most critical need, we are continuing our mission by helping as many schools, universities, and employers get the testing resources and capabilities they need to get back to.
How do celestial bodies warp the fabric of space-time and interact with each other?
ABOUT THIS EXPERIMENT
We tend think of gravity as a force of attraction, but it’s also been described as a curvature of space-time in the presence of mass. This National Science and Technology Medals Foundation interactive invites you to bend the fabric of space-time and observe the resulting gravitational forces. By adjusting the variables of mass, distance, and velocity, you can trigger orbits, collisions, and escape velocities in space.

Gravity Lab Login
Gravity Lab is a gravity simulator for iPad. 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. The positions and velocities of all the particles are recalculated in real time. 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. 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.
Gravity Lab is a great tool to explore the laws of nature that govern everything in the universe. 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. For us, standing here on Earth, gravitational forces always point down. Should you, however, spend a day as a heavenly body, your perception would be completely changed.
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.
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. All these concepts can be demonstrated using Gravity Lab.
What you can do:
- create your own solar system
- demonstrate complex interaction patterns of multiple massive bodies
- collide massive bodies and demonstrate the conservation of momentum
- display vectors of acceleration due to gravitational forces and observe the acceleration of orbiting bodies
- observe first two of the three Kepler's laws of planetary motion
- demonstrate gravitational slingshot (gravity assist) for increasing the spacecraft's velocity
- observe effects of changing gravitational constant on the gravitational field using 'Gravity well' mesh type
How to use
Gravity Lab Phet
- create bodies by selecting the desired mass and drawing a vector of initial velocity using your finger
- tap to create a stationary body
- pinch to zoom
- use two fingers to pan
- toggle Acceleration on/off to display direction and relative size of body's acceleration (same as the direction of the forces)
- reset particles and zoom level
