If the earth is like this sphere, why don't we go down?
We
are constantly pulled (attracted) towards the earth's surface due to
gravitational force (u). So even though the earth is like a sphere, we do not
sink down.
Will people be standing upside down
in Argentina?
The
size of our earth is huge. Hence, even though the earth is round, there is no
'up' or 'down' on the earth as we live on a very large flat area. This is why
Argentines tend to stand up straight.
How did you eat your food? How did you
drink the water? What happened to the ball when you threw it up?
We
floated and our food floated. They caught the food and ate it while floating.
The water was floating like a drop. He caught the drops of water and drank the
water. Throw the ball up and it floats and hangs under the ceiling.
Do you think there are any
similarities between the sphere and the photograph of this Earth? How is it
different?
In
the sphere and in the photograph of the earth, the earth appears to be round.
This is equality. The difference is that it is difficult to identify countries
and places in a photograph of the Earth. When the borders of the countries are
shown in the globe, they can be easily identified.
Sunita would have been able to
distinguish Pakistan, Nepal and Myanmar separately when she was looking at the
earth from space?
No,
Sunita would not have been able to distinguish between Pakistan, Nepal and
Myanmar while looking at the Earth from space. Because the lands of the
countries on the earth are visible from space, but it is not known to which country
that land belongs.
Look carefully at the night sky for
five minutes.
(1) What can you see?
Moon
and stars are visible in night sky. Also, light streaks of the falling star and
some planets are visible.
Do you see anything moving in the
sky? What do you think it could be? Star, Comet or Satellite? (Artificial
satellites are used for TV, telephone and climate.) Learn more about it.
According
to me the shiny object in the sky which is seen moving continuously fast is an
artificial satellite. Often a bright bright lisotto is seen in the sky. What we
call a 'shooting star'. These are called meteorites.
Information about artificial
satellite:
An
artificial satellite is a man-made satellite that orbits the Earth in a fixed
orbit, in 1957 Russia first launched an artificial satellite, Sputnik-1. After
this satellite many artificial satellites have been put into space.
India
launched its first artificial satellite - Aryabhata on 19 April 1975 from a
Russian space station (cosmodrome). Since then India has launched many
artificial satellites from its space station.
Have you ever seen the moon at 12
noon? Why can't we easily see the stars and the moon during the day?
No,
I have never seen the moon at 12 noon. The sun gives a lot of light and heat to
the earth. As the light of the stars and the moon is very dim compared to the
bright light of the sun does not appear Hence we easily see stars and moon
during the day Can't see..
(1) Children
always fall down slides. Why not go up on the slip? If this slippery Sunitan
was in a spacecraft, could children do it? What?
Children always talk from top to bottom Caused
by force. Because, the force of gravity acts from above. This slide would have
been in Sunita's spaceship .. the children would not have been able to slide
down the slide and float in the air. Because there is no gravitational force in
space. Answer: The Sun is very close to the Earth as compared to the stars.
Seeing Earth from space, Sunita
said, “Different countries cannot be seen separately from here. These borders
are on paper. We made it.” What do you understand by this statement?
Through
this statement of Sunita, I understood that the borders of countries are
created by humans for their own selfishness. Nature has not created any borders
on earth. In the eyes of nature we all (the whole world) are inhabitants of the
earth. We are connected with the spirit of 'Vasudhev Kutumkam
What is the relationship between
Sun, Earth and Moon?
(1)
Sun is a star. (2) This of Earth Solar System is a planet. The earth revolves
around the sun. (3) This is the satellite of Moon Earth. The moon revolves
around the earth. (4) One of the planets of the Sun is the Earth and the
satellite of the Earth is the Moon. (5) Sun the largest, Earth smaller than it
and Moon smaller than it. Thus, all three are celestial bodies
Give insight into lunar arts.
(1)
Moon has no light of its own. The sun shines on the moon and the moon appears
illuminated. (2) The moon does not appear equally illuminated every day. The
illuminated portion of the Moon fluctuates in size. This changes the shape of
the illuminated part of the moon. These are called moon arts. (3) From Sud Ekam
to Poonam 1. The size of the illuminated visible portion of the Moon gradually
increases. On the day of Poonam, the moon appears perfectly round. (4) After
poonam = vada ekam the moon's art gradually diminishes and on amasa day the
moon is not visible at all.
Give a brief introduction about
Earth.
Earth
is one of the eight planets in the solar system. of the solar system Life
exists only on earth. Earth, Venus and Mars It is located between the planets.
It is not perfectly round. But like an orange is round. The earth rotates on
its axis as well as around the sun. It completes one turn on its axis in
twenty-four hours. Day and night occur due to this diurnal motion of the earth.
Earth approx Completes the orbit of the sun in 365 days.
How did Sunita Williams see Earth
from space? What thoughts did he have there?
Sunita
Williams saw Earth from space and found it very beautiful and attractive. Also,
he saw the earth as illuminated like the moon from the earth. Many thoughts
came to his mind. Describing it, he said that looking at the earth from a great
distance, only its land or sea can be recognized. No one can see different
countries. We have divided the countries. The borders we create in maps are in
our minds. They want us to think about where the borders actually are.
Briefly explain the difficulties
faced by an astronaut traveling in a spaceship.
While
traveling in a spaceship, an astronaut has to face the following 7
difficulties: (1) An astronaut experiences weightlessness. ” Hence the
astronaut does not float in space like a balloon in a spaceship but moves
around. (2) The food placed on the table and the dish floating in space are 1.
So one has to swim to and fro to catch it. (3) He has difficulty in drinking
water and taking food. The water in the cup floats in space
as the cup moves.
