Los astronautas NO FLOTAN! Descubre por qué!

The video explains the International Space Station (ISS) as a collaborative artificial satellite that has been inhabited since 2000. It discusses why astronauts appear to float, clarifying that gravity still affects them. The ISS orbits Earth at 400 km, experiencing 88% of Earth's surface gravity. The video uses Newton's laws to explain gravitational acceleration and describes how the ISS and its crew are in a state of continuous free fall, maintaining orbit by moving at a speed that matches Earth's curvature. This concept is likened to throwing a stone with enough force to keep it in orbit.

What is the primary reason astronauts appear to float inside the International Space Station?

• There is no gravity in space.

• The ISS is moving at a constant speed.

• The ISS is in a state of free fall.

• Astronauts are using special equipment to float.

What is the gravitational acceleration experienced by the International Space Station compared to Earth's surface?

• It is the same as Earth's surface gravity.

• It is 88% of Earth's surface gravity.

• It is 50% of Earth's surface gravity.

• There is no gravitational acceleration at that height.

According to Newton's formula, what does 'R' represent in the context of gravitational acceleration?

• The mass of the Earth.

• The radius of the Earth plus the height of the ISS.

• The distance between the ISS and the Moon.

• The speed of the ISS.

What happens when you throw a stone with just the right speed so that it keeps falling around the Earth?

• It will eventually fall back to Earth.

• It will escape Earth's gravitational field.

• It will enter a stable orbit around the Earth.

• It will hover in place above the Earth.

How do astronauts perceive their environment while in orbit on the ISS?

• As a strong gravitational pull.

• As a stationary environment.

• As a constant upward force.

• As a sensation of weightlessness.
