Objects tossed around by space travelers appear to move slowly due to the absence of air resistance and the effects of microgravity. In space, there is no atmosphere or significant air pressure to impede the motion of objects. On Earth, when we toss an object, air resistance acts upon it, gradually slowing it down and causing it to fall to the ground relatively quickly.
In the microgravity environment of space, there is no gravitational force to provide a constant acceleration towards the ground. Instead, objects continue to move with the same speed and direction unless acted upon by an external force. When an astronaut tosses an object in space, it will retain its initial momentum and continue moving at a relatively constant speed. However, since there is no friction or resistance to oppose its motion, it appears to move slowly because there are no forces acting to accelerate or decelerate it significantly.
Additionally, in the microgravity environment, astronauts themselves are weightless and experience a sensation of floating. When they toss objects, they do not have a solid surface or friction to push against, which can affect the force and speed of their throws. As a result, the objects may not reach the same velocities as they would on Earth, making their movements appear slower.
