gravity, n.Trivia

Earth’s gravity is about six times stronger than that on the surface of the Moon.

If you weighed 100 pounds of Earth, you 1d only weigh 38 pounds on Mars.

The moon is constantly acting on us. When it is directly overhead, we weigh slightly less

Astronauts are taller when in space

Isaac Newton never said the idea of gravity came to him when an apple fell on his head. He said he sat "in a contemplative mood" and "was occasioned by the fall of an apple".

Astronauts report letting go of objects in mid-air for months after returning to earth, fully expecting them to float.

Gravity overtakes buoyancy at around 20 metres underwater and you start falling towards the centre of the earth.

Birds need gravity to swallow

Bats hang upside down because their legs are too weak to support their weight

In zero gravity, a candle's flame is round and blue.

A hole through the middle of the earth would take 42 minutes to fall through.

Ants can survive a fall from any height because their terminal velocity isn't great enough to kill them.

Sir Isaac Newton was 23 when he discovered the law of gravity

The moon is in fact falling to the earth in exactly the same way that the apple falls to the earth

Gravity is actually the weakest of the universe’s four fundamental forces. We defeat gravity all day long.

Astronauts cannot cry in space because tears can't flow in zero gravity

Height is constantly changing throughout the day--- we are 1-2 centimeters taller in the morning than at night
