In space, if the ISS is traveling at 17,150 miles per hour how does it look so stationary in the video from the Dragon capsule. Also How does it dock so precisely when it is moving so fast.
In: Physics
Because the capsule is matching speed. Relative to the surface of the earth, both the capsule and ISS are travelling at the same speed. Relative to each other, they are barely moving as they speeds are matching and at the point of docking, they are not moving at all.
