Question

What does defying gravity mean?

Answer 1

Hint: Gravitation is a natural phenomenon in which objects with mass or energy are attracted towards other objects. Due to moon gravity tides are formed in the ocean and on earth gravity will give mass to objects. Effects of gravity will be weaker when the object moves further and gravity is a universal force.

Complete step-by-step solution:
Some examples of culture that magicians the way they appear to defy gravity by floating some person in the air without support and also by making use of gravity magicians will do black magic. Magicians always use threads or wire to support the person but they will create an illusion that the person is floating without support.
Gravitational attraction of the sun is defy to appear by the earth but due to some complex physics our initial momentum given to the earth is enough to keep us in orbit when the solar system is formed.

Additional information: Newton’s law of universal gravitation states that every object attracts every other object in the universe with a force and is directly proportional to product of their masses and inversely proportional to the square of the distance.
SI unit of force is newton (N).

Note: Students in space there will be a small amount of gravity and so gravity in space is not zero. Gravitational force that will hold the solar system together and gravitational constant is equal to$6.67\times {{10}^{-11}}N k{{g}^{-2}}{{m}^{2}}$ and in a hollow spherical shell the gravitational force on the object will be zero. Force is a vector quantity.
