What would happen if the earths gravitaional force decreased by half?

Answer 1

It is impossible to foresee all effects, though some are foreseeable. First, everyone will be lighter and you will be able to jump higher, move easier etc. Buildings dependent on that force of gravity could collapse. Pipelines burst because pressure outside the pipe has decreased and hydro-power plants shut down or are very inefficient since the water loses the driving force of gravity. The moon speeds up the process of moving away from the Earth (yes it is happening). As the moon leaves Earth plummets into catastrophic climate changes as the Earth is pulled between the Sun's and Jupiter's gravitational forces as the moon is no longer there to hold the Earth stable. You get the point.

Answer 2

If the Earth's gravitational force decreased by half, objects would weigh less and feel lighter. This could lead to changes in orbits of satellites and celestial bodies, potentially impacting their paths and stability. Additionally, the reduction in gravitational force could affect atmospheric retention and potentially influence weather patterns.
