During the launch, astronauts in a space shuttle experience a sensation of weightlessness for a short period due to the force of gravity being canceled out by the acceleration of the shuttle. However, this weightlessness is not the same as the zero gravity experienced in orbit, as it is a result of the shuttle's motion rather than being in a true microgravity environment.
This is known as free fall or microgravity. In this state, astronauts and objects inside the shuttle experience a sensation of weightlessness because they are falling at the same rate as the shuttle around the Earth, creating the illusion of being in a state of weightlessness.
Astronauts inside a falling shuttle experience weightlessness because they are in a state of free fall alongside the shuttle. This means both the astronauts and the shuttle are falling together at the same rate, so there is no sensation of hitting the ceiling despite the lack of gravity.
As the space shuttle orbits the Earth, both the shuttle and the astronauts inside experience the same gravitational acceleration towards the Earth. This gives the sensation of weightlessness because everything inside the shuttle is falling towards Earth at the same rate, creating the feeling of floating.
As the space shuttle orbits the Earth, both the shuttle and the astronauts experience free fall, resulting in a state of weightlessness. This occurs because they are both accelerating toward the Earth at the same rate due to gravity. Although gravity is still acting on them, their horizontal velocity allows them to continuously fall around the Earth rather than directly toward it. This creates the sensation of floating for the astronauts inside the shuttle.

Astronauts don't hit their heads on the ceiling of a falling shuttle because they experience microgravity, which creates a sensation of weightlessness. In this state, both the astronauts and the shuttle are in free fall together, moving at the same rate and direction. This means that there is no relative motion between the astronauts and the shuttle interior, preventing them from contacting the ceiling.

Weightlessness
At what altitude does the Earth's gravity no longer have an effect on the astronauts or the space shuttle?
on humans
The effects of weightlessness on humans is explored during the work done by astronauts. This helps with advancements in medical and technological fields.
