Question

What is the difference between flying around the earth and orbiting the earth on the ISS? Which do you think takes more energy, and why?

Answer #1

You can't fly around the earth because in space around the earth there is earth gravity which will attracts you towards the earth and you will fall into the earth but you can fly on the earth because if you want to fly you need atmosphere which is on the earth .That's why by applying proper thrust you can fly on Earth .

Orbiting means your going to orbit around the earth in space with particular time period and you don't need any energy to orbiting around the earth because here the gravitational Force of Earth will going to balance your centripetal force (it is force acting when you orbit around the earth in circular orbit) and hence you don't need any energy to orbiting around the earth but while flying on Earth you need energy .

And hence flying takes energy and on other hand orbiting around the earth doesn't require energy .

7) The earth and the 500-kg satellite orbiting around the earth
at
the height 300 km above the earth surface Find the
gravity force, with which the earth is acting on the satellite.

How does the ISS stay in orbit?
Explain using relevant physics concepts why the ISS astronauts
practice underwater for their task of assembling the ISS in a low
Earth orbit (LEO)? How similar do you think is moving under water
to moving in the ISS? What are some important differences?

Dave is sitting on a spaceship orbiting the Earth (1 au from the
sun). At this distance, his solar panels gather an intensity of
1000 (watts/m^2) from the Sun's radiation. Dave wants to gather
enough energy to run his coffee machine which needs an intensity of
20 (watts/m^2)
Question 1:
Dave flies to Saturn (which is approximately 10 au from the sun)
and at somewhere along the way his coffee machine no longer gets
enough power. What intensity do his...

A space shuttle is orbiting around Earth, at distance r = 6.77 x
106 m away from the center of Earth. At this distance,
gravitational acceleration is equal to g = 8.69 m/s2.
There is an astronaut aboard the space shuttle, she is 1.70 m tall.
The difference in gravitational acceleration betweeen her feet and
her head is Δg = -4.36 x 10-6 m/s2
Considering the above information, answer parts a, b, c, d, and
e below. Include your explanation...

You want to put a satellite in a geosynchronous orbit around the
earth. (This means the asteroid takes 1 day to complete a turn
around the earth.)
(a) At what height above the surface do you need to put it?
(b) How fast is it moving?
(c) How does the answer to (b) compare to the escape speed from the
earth, for an object at this height?

A satellite (mass 2400 kg) is orbiting the Earth, with a speed
of 7500 m/s. What is the height of this satellite above the Earth's
surface?
Note: you may find the following information useful. The
universal gravitational constant is 6.67x10-11
Nm2/kg2 ; the mass of the Earth is 6.0 x
1024 kg; the radius of the Earth is 6.4 x 103
km.
can you please show work if you can? I APPRECIATE YOU!!!

Suppose there were a planet in our Solar System orbiting at a
distance of 0.5 AU from the Sun, and having ten times the mass and
four times the radius of Earth. For reference, the Earth has a mass
of 5.97 × 1024 kg and a radius of 6,378 km.
a) Calculate the density of this hypothetical planet.
b) Based on your answer from part a), what do you think this
planet would be made of? Explain your reasoning.
c)...

What is the difference between piloting, path integration (dead
reckoning) and true navigation? Which one do you think is more
helpful to a migrating animal?

What is the total kinetic energy of the Earth due to its
rotation around the sun and it’s spin about its own axis?

Compare two objects in orbit around the earth. One is a
satellitein an orbit relatively close to the earth’s surface, and
the other is the moon. Assume both have circular orbits. Which of
the orbiting bodies has the largest centripetalacceleration? What
is the centripetalacceleration of the moon?How would your answer
change if Newton’s law of gravity was wrong and all bodies
experienced a constant force independent of distance?
