If you have car sickness, but only when you look at a book or screen while its moving, is there an exact terminology for it? and sorry if i chose the wrong subject for this, im new to asking questions.

The exact terminology would be motion sickness, not car sickness.

Explanation:

Reading a book or using your phone while in or on any moving object can cause motion sickness.

With motion sickness your body is moving in space, such as in a moving car or on a boat rocking at sea, but your eyes aren’t getting the same information. Kind of like when you are reading while in a car: Your eyes are focused on the words, thinking you’re stationary, but the rest of your body is sensing the movement of the car.

Motion sickness is basically a sensory conflict.

Now there is something called cybersickness, which is almost the same as motion sickness but it pertains more to using/ watching moving pictures on a screen while your body is stationary.

It has opposite sensory effects than motion sickness, where your eyes think you are moving but your body is not.

weathering is the answer.
