Is Rotational Motion Possible in a Straight Line?

[QAZI]

can a body moving in a straight line be in rotational motion as well?

Sure, why not? The center of mass of a body can move in a straight line, while the body also rotates about the center of mass.

Yeah I actually just learned about this in my class. An object can undergo both translational motion and rotational motion. For example, imagine a baton twirling in the air. The center of mass of the baton travels a certain horizontal distance (translational motion), but it also has a torque applied about its center of mass which causes rotational motion.

Can you give some examples?
thanks anyways.

yeah,but... are there some more examples?

okay, there are plenty of examples: spinning ball, wheels of a car, any rotating object in a car, etc

can we say planets or sun or galaxies are also some of the examples?
thanks anyways.
