Rotation in Space: Rod, ISS, Yoyo Motion

In summary, the conversation discusses the potential rotation of a rod in the ISS when force is applied to one end, as well as the rotation of a yoyo from a floating position. It is suggested that the rod would rotate about an axis at the other end, while a stick thrown in the air appears to rotate about its center.

We have a rod and keep floating in ISS. If we tap giving force at one end, will it,
1. Rotate about an axis or
2. Has translational and rotational motion.
If it rotates, where is the axis?

I have interest in yoyo motion too. From YouTube, they spin them while holding. Can we rotate yoyo from floating position?.

What do you think?

I think it rotates with the axis of the other end, since the near end moves first followed by nearest mass till the other end.
But if we throw a stick to the air it looks like it rotates about the center.
 

1. What is rotation in space?

Rotation in space refers to the movement of an object or system around a central axis or point in a circular or elliptical path.

2. How does rotation affect objects in space?

Rotation can affect objects in space in various ways, depending on their size, mass, and distance from the central axis. For example, smaller objects may experience a faster rotation rate, while larger objects may have a slower rotation rate. Rotation can also cause objects to experience centrifugal force, which can impact their trajectory and stability.

3. What is the difference between rotation and revolution?

Rotation refers to the spinning of an object around its own axis, while revolution refers to the movement of an object around another object or point. For example, the Earth rotates around its own axis, but it also revolves around the Sun.

4. How does rotation impact the International Space Station (ISS)?

The ISS rotates around the Earth at a rate of about 17,500 miles per hour. This rotation helps to keep the ISS in orbit and allows it to maintain a constant distance from the Earth.

5. How do astronauts use yoyo motion in space?

Astronauts can use yoyo motion in space to simulate gravity and exercise their muscles. By holding onto a yoyo or other weighted object and pulling it back and forth, they can create resistance and work their muscles in a similar way to weightlifting on Earth.
