Why the astronauts suddenly fly forwards and then suddenly moves backwards on there seats?
Astronauts experience sudden forward and backward movements in their seats due to changes in acceleration and deceleration during launch and re-entry. When a rocket launches, the rapid acceleration pushes them back into their seats, while during re-entry, the deceleration from atmospheric drag can cause them to move forward. These shifts in motion are a result of the forces acting on their bodies as the spacecraft changes speed and direction.

What celestial object moves backwards among stars?
The celestial object that appears to move backwards among the stars is a planet in retrograde motion. This happens when a faster-moving planet "laps" a slower-moving outer planet from the viewpoint of Earth, causing it to look like it is moving backwards relative to the fixed stars in the sky.
Why are astronauts on the International Space Station weightless?
Astronauts on the International Space Station (ISS) experience weightlessness because both the ISS and the astronauts are in free fall towards Earth. Although the ISS is constantly falling due to gravity, it also moves forward at a high speed, creating a continuous orbit around the planet. This state of free fall creates a sensation of weightlessness for the astronauts inside, as they are effectively falling along with the station. Thus, they experience microgravity, leading to the feeling of floating.
Which explains why astronauts seem weightless in orbit?
Astronauts seem weightless in orbit because they are in a state of free fall, along with their spacecraft. As the spacecraft moves forward at high speed, it simultaneously falls toward Earth due to gravity. However, because it's also moving horizontally, it keeps missing Earth, creating a continuous free-fall loop. This condition results in a sensation of weightlessness for the astronauts inside.
Why the astronauts feel weightlessness inside the orbiting spacecraft?
Astronauts feel weightlessness inside an orbiting spacecraft because both the spacecraft and the astronauts are in a continuous state of free fall towards Earth. As the spacecraft travels at high speeds in orbit, it falls towards the planet but also moves forward, creating a curved path that matches the curvature of the Earth. This balance between gravitational pull and forward motion results in a sensation of weightlessness, as there is no support force acting on the astronauts. Essentially, they are in a state of microgravity, experiencing the effects of gravity but not feeling it as they would on the surface.
What do astronauts do with their poop?
Astronauts' poop is sealed in bags on the International Space Station and stored until it is trashed in a spacecraft or cargo vehicle that burns up upon re-entry into Earth's atmosphere. Some missions have experimented with recycling waste into useful resources.
What moves backwards and forwards in sound?
The atoms of the particular medium in which the sound is produced moves backward and forwards in sound.
What moves backwards and forwards but doesn't go anywhere?
A swing!
When sound is moving forwards and backwards what is it called?
When sound moves forwards and backwards rapidly, it is called oscillation. This back-and-forth movement is what creates sound waves.
When a truck collides with van van moves backwards and truck forwards why?
The truck is heavier
What bird can only move backwards?
no bird can only move backwards! only a hummingbird has the ability to move backwards but it also moves forwards and left to right!
What moves backwards and forwards in a straight line?
A train moves backwards and forwards in a straight line along its tracks. Similarly, a piston in an engine operates in a straight line, moving back and forth to generate power. Additionally, a sliding drawer can also move in and out along its guides in a straight path.
What moves backwards and forwards?
Is this a serious question? Cuz' lots of things do. :p
When you add integers do you go forwards or backwards?
When you add integers, you generally move forwards on the number line if you are adding positive integers and backwards if you are adding negative integers. For example, adding 3 to 5 moves you forward to 8, while adding -2 to 5 moves you backward to 3. The direction depends on the signs of the integers involved.
What is tympanum system?
The tympanic membrane, or ear drum. A thin piece of skin inside the ear that moves backwards and forwards when sound waves reach it
What moves backwards and forwards in an ear?
The eardrum (tympanic membrane) moves backward and forward in response to sound waves, which then causes the tiny bones in the middle ear to vibrate and transmit the sound to the inner ear.
What moves forwards and backwards but has no legs it cannot talk it cannot walk it doesn't slither or crawl across the floor either It comes in a different shapes sizes and colours What is it?
A door! :)
