Can a body spinning about its own axis, be able to move (translational motion) along a straight line?

Suppose a body is spinning about its own axis, and it is free to follow its path. Now what we get to see that such bodies (along with the spin) tends to move in a circular path. In any case, is it possible, that the translational motion the body shows be along a straight line? Explain.Can a body spinning about its own axis, be able to move (translational motion) along a straight line?Yes.

Bodies in space tend to orbit one another because of the effect of gravity.

This is why they move in a circular path (gravity), not because they are spinning.

Two meteors can be spinning about their respective axes and be moving in a straight line toward each other.

Another example:

try spinning a (heavy) top on a relatively frictionless surface (such as a wet, glass-top table) and then tilt the table so that the top slides down. In the absence of friction the top will move straight down the table top (in a straight line).



Another example:

A pinball in a pinball machine will roll straight down the table if it is not given an initial push.Can a body spinning about its own axis, be able to move (translational motion) along a straight line?i think if the direction of motion coincides with the rotational axis, maybe? like a bullet?
