This highly interactive Exploriment App lets you explore the effect of gravity on weight and mass on different planets. You can also explore the effect of altitude on weight and mass and even of depth below the Earth’s surface. Use variety of instruments and free fall of a body to understand the effect of gravity in different scenarios. This app provides ample opportunities to try out various scenarios and compare the results across planets and varying altitudes, including scenarios of micro-gravity and near-weightlessness.

The Exploriments Series of interactive simulation-based tools makes conceptual learning in science an engaging and insightful experience. Visit www.exploriments.com to know more.


Weight and Mass on Different Planets

--- Interactively weigh objects and compare mass on Earth, Moon and other planets using weighing scale, spring scale and pan balance

Effect of Altitude on Weight and Mass

--- Select a planet and then compare weight and mass at different altitudes

--- Drop a body and observe how the speed of fall changes as the altitude increases

--- Explore near-weightlessness in an environment of extremely weak gravitational pull

Effect of Depth below Earth surface on Weight

--- Almost everyone knows what happens to weight as you go to high altitudes, but it can be a surprising discovery to find out what happens to weight if we go towards the center of the Earth

--- A trip down an imaginary tunnel dug through Earth, lets you explore how gravity changes as you move towards the Earth’s center

Additional Features:

--- Highly interactive simulation

--- Easily manageable environmental settings such as selecting a planet, changing the altitude and changing the depth below surface of a planet

--- Intuitive visual experience supported by numerical and graphical output

--- Effective comparison between different settings

Needs update


Great app but no longer works on my iPad is not compatible with iOS 11

For a free app it does some simple differences of putting masses on different scales. Nice, but it is not intuitive on how to change planets / effects of gravity ( unable to work it out). Just worked out the reason was that the planet selectors did not work the first time. Also I'm under the impression that mass is the same amount no matter what planet you are on (as it is a measure of an amount of matter). The app does not make this obvious when moving the scales from earth to the moon, and shows a change in mass without an explanation that in reality it should not occur.

Locks out


Looks nice but locked after a couple of tries. Red cross and no further choices possible.
