Question

If you watch some old movies of astronauts walking on the Moon, you will notice that these folks were able to move around without difficulties even though they were wearing massive spacesuites. Why?

Answer 1

Astronauts are able to move around without difficulties in space because they experience weightlessness, which is caused by being in freefall. In freefall, gravity is pulling the astronauts towards the Earth, but they are also moving fast enough to never hit the surface. This allows them to float and move around in their spacesuits.

Step-by-step explanation:

Astronauts are able to move around without difficulties even though they are wearing massive spacesuits because they are experiencing weightlessness in space. Weightlessness occurs when an object is in freefall, meaning that gravity is pulling it toward a larger mass (like the Earth) but it is also moving fast enough horizontally to never hit the surface. In space, astronauts and objects float because they are essentially falling around the Earth while traveling at a high speed.
