You feel weightless in water because your body is partially supported by the buoyancy of the water. This buoyant force counteracts the force of gravity, reducing the effective weight you feel. Additionally, the viscosity of water helps to support your body's movements, making it easier to move and feel lighter in the water.

Why do you feel lighter when you swim?
When you swim, the water supports your body weight, making you feel lighter. Water buoyancy helps to counteract the force of gravity, resulting in a sensation of weightlessness as you move through the water.
Distinguish between apparent weightlessness and true weightlessness?
Apparent weightlessness occurs when an object is in free fall, making it feel weightless due to the absence of support forces. True weightlessness occurs when an object is at a point in space where the gravitational pull is negligible, resulting in a complete absence of gravitational forces acting on the object.
How do you put weightlessness in a sentence?
Weightlessness is experienced by astronauts in space due to the absence of gravitational forces.
What is the difference between weight and weightlessness?
Weight is the measure of the force of gravity acting on an object, while weightlessness is the sensation experienced when an object is in free fall and does not feel the normal force of gravity. In weightlessness, objects and individuals float freely and do not experience the sensation of weight.
If a cable snaps in an elevator and starts falling will the person inside float?
No, the person inside the elevator will not float. Objects in freefall experience weightlessness, but the person will still accelerate downward due to gravity. The experience will feel like weightlessness, but they are still subject to gravity's pull.
How is weightlessness different from swimming?
Weightlessness means having little or no weight; not experiencing the effects of gravity. The difference between weightlessness and swimming is that during swimming you feel your weight less but you still have weight, you are still being subject to the same amount of gravity. Your weight and gravity are what is keeping you in the water.
What do you feel in space?
-- weightlessness -- isolation -- disorientation -- nausea
Why do you feel light on your feet when standing in a swimming pool with water up to your armpits?
Because the deeper the water you are standing in is, the more pressure the water pushes on you, and this pressure pushes you upwards, making you feel a sense of lightness or weightlessness.
Why do you feel lighter when you swim?
When you swim, the water supports your body weight, making you feel lighter. Water buoyancy helps to counteract the force of gravity, resulting in a sensation of weightlessness as you move through the water.
What is similar to weightlessness?
Being under water.
Why do astronauts in orbit feel weightlessness?
they are falling through space around earth
Distinguish between apparent weightlessness and true weightlessness?
Apparent weightlessness occurs when an object is in free fall, making it feel weightless due to the absence of support forces. True weightlessness occurs when an object is at a point in space where the gravitational pull is negligible, resulting in a complete absence of gravitational forces acting on the object.
How do you experience weightlessness on earth?
You can approximate weightlessness in a swimming pool. NASA astronauts practice maneuvers under water.
What has the author Noel C Hunt written?
Noel C. Hunt has written: 'Positive pressure breathing during water immersion' -- subject(s): Water immersion, Weightlessness, Pressure breathing, Weightlessness simulators
What does weightlessness?
Weightlessness is the effect that astronauts enjoy in space.
How could you use the word weightlessness in a sentence?
you are so weightlessness
What does weightlessness mean?
Weightlessness is the effect that astronauts enjoy in space.
