The full information about the absence of weight or weightlessness is explained on Fun Facts about Zero Gravity. You may feel weightless when you have a free fall due to the absence of g-force acceleration. People often call the zero g-force as zero-g. The people will enjoy a sensation of weight when they are inside a space ship with zero gravity. Let us find out more other interesting facts about zero gravity below:
Fun Facts about Zero Gravity 1: the free fall
Having a free fall will give an impact to the body for it is not a stress free act. The tidal effect is experienced by the body due to the non-uniform gravitational field.
Fun Facts about Zero Gravity 2: the level of tidal effects
The level of tidal effect on earth is relatively small when it occurs in small object like spacecraft and human body. However, it can produce major tidal effect if the location is close to a black hole.
Fun Facts about Zero Gravity 3: ways to avoid weightlessness
Some ways can be conducted to avoid weightlessness. You can do some activities such sitting on a chair or even standing on the ground.
Fun Facts about Zero Gravity 4: a plane
When you are inside a plane to fly, the weightlessness can be avoided because the wings will serve as the support force.
Fun Facts about Zero Gravity 5: the cause of tidal forces
The tidal forces occur under two conditions. One is due to the presence of gravitation gradient. Another reason is due to the non-uniform gravitational field.
Fun Facts about Zero Gravity 6: earth and gravitation
The non-uniform gravitation field is spotted on earth due to the presence of tides. However, earth is in free fall condition. The presence of tides is influenced by the moon.
Fun Facts about Zero Gravity 7: the sun and moon
Actually, the sun also affects the gravitational field of earth, but it only gives small amount of tidal effect.
