Why do astronauts orbiting the earth experience weightlessness even though they are still within the earth's gravitational field?
When something is orbiting the Earth, it is actually falling toward the Earth. But because a space shuttle has such a great velocity (speed w/ direction) it misses hitting the Earth's surface. Image you throw a Baseball. The baseball follows the path of a curve called a parabola, but the parabola is actually part of an eclipse (elongated circle). Now image if you threw the baseball so hard that when it fell toward the Earth, it actually missed the "edge" of the Earth following the path of the eclipse around the Earth. That baseball would then be launched into orbit. (Of course you would have to throw this baseball at a speed of 11 km/s).

Who was the astronaut who experience weightlessness while orbiting the earth?

True or false. Orbiting astronauts feel weightless because they are beyond the gravitational pull of the earth?
False.Orbiting astronauts feel weightlessness since the gravitational pull of the Earth is balanced by the centrifugal force due to the circular orbital motion, which balance each other out since the spaceship is in orbit. That is, the weightlessness is because of no net force on the astronaut.In a nutshell, if you are orbiting, then irrespective of what height you're doing it, you'd be weightless.
Why orbiting astronauts appear to be floating is that they are experiencing?
Yes that is what they are experiencing.
You are explaining to friends why astronauts feel weightless orbiting in the space shuttle and they respond that they thought gravity was just a lot weaker up there?
It depends. If there is an orbit, the motion may provide a force in the opposite direction as the gravity, leading to weightlessness. Of course, the force goes down as 1/(r*r), where r is the radius of separation.
When astronauts enter earth gravity how close are they?
Astronauts do not completely leave the earth's gravity, they only enter a state of free fall orbiting the earth causing weightlessness. The astronauts that went to the moon technically do not leave the earth's gravity, they simply get close enough that the moon's gravity has a stronger effect than that of the earth's gravity. The distance at which this happens is called the sphere of influence. The moon's sphere of influence is approximately 66 000 km, this would be about 315 000 km away. In the Sun earth system, the earth's sphere of influence is 925 000 km. Therefore if you are within 919 000 km of the earth's surface, it's gravity will be the primary gravitational force experienced. The only exception is if you come within 64 500 km of the moon's surface.

What is true weightlessness?
True weightlessness refers to the sensation experienced by objects or individuals when they are freely falling in a vacuum environment, without any external forces acting on them. This occurs when the force of gravity is canceled out by the acceleration of the object. Astronauts in space experience this sensation due to their spacecraft orbiting the Earth.
Why do astronauts on space orbiting earth float?
Astronauts in orbit around Earth experience weightlessness because they are in a state of free fall. While they are moving at high speeds tangentially to the Earth’s surface, the gravitational pull of the Earth keeps them falling towards it. However, because they are also moving forward, they continuously "fall" around the Earth rather than directly towards it, creating the sensation of floating. This condition is known as microgravity.

Why do astronauts on space station orbiting earth float?
Astronauts on the International Space Station (ISS) experience weightlessness because both the station and the astronauts are in a state of continuous free fall towards Earth. While gravity still acts on them, the ISS travels forward at a high speed, creating a curved path that matches the curvature of Earth. This balance between gravitational pull and forward motion results in a sensation of floating, commonly referred to as microgravity. Thus, they are not truly "floating" but rather falling around the Earth.
Why do astronauts appear weightless and space?
Astronauts appear weightless in space because they are in a state of free fall, orbiting the Earth along with their spacecraft. This creates a condition known as microgravity, where both the astronauts and the spacecraft are falling towards Earth at the same rate, resulting in the sensation of weightlessness. Although gravity is still present, the lack of a solid surface to push against leads to this floating experience.
what is it called when an orbiting astronaut and feels no gravity?
Weightlessness.
How do you explain the apparent weightlessness of orbiting objects?
you cant
Weightlessness occurs when an object applies a reaction force to another object?
Weightlessness occurs when an object is in free fall where gravity is the only force acting on it. The sensation of weightlessness is experienced because both the object and the observer fall towards the center of gravity at the same rate. This state is commonly observed in astronauts within a spacecraft orbiting the Earth.
What gravitational effects do you experience in an orbiting space station?
None. Inside the space shuttle is regulated.
What do we call it when the gravitational forces on an object in space are balanced?
When the gravitational forces on an object in space are balanced, we call it zero gravity or weightlessness. This occurs when the object is in free fall or orbiting the Earth without any external forces acting on it to counteract gravity.
Why do astronauts appear floating inside a spaceship?
Astronauts appear to be floating inside a spaceship because they are in a state of free fall, often referred to as microgravity. The spaceship is orbiting the Earth, and both the spacecraft and the astronauts inside are falling towards the planet at the same rate. This creates the sensation of weightlessness, allowing them to float freely within the cabin.
