Here is a plank in empty space(There are no forces except one) .Someone is pushing it on a side.Will it rotate or Move straight in the direction of the force?

What do you think? Apply Newton's 2nd law for translation and for rotation.Here is a plank in empty space(There are no forces except one) .Someone is pushing it on a side.Will it rotate or Move straight in the direction of the force?
I don't quite understand that.What do you think? Apply Newton's 2nd law for translation and for rotation.
OMG!What's ##\tau = I\alpha## ?Write down ##F = ma## and ##\tau = I\alpha## for the system you drew.
OMG!What's ##\tau = I\alpha## ?
See: Newton's 2nd Law: RotationOMG!What's ##\tau = I\alpha## ?
I have not heard about anything about the moment of inertia or angular acceleration.Anyways,The plank will rotate,Am I right?
The motion of the plank will be a combination of the translation of the center of mass plus rotation about the center of mass. It will rotate as well as translate.I have not heard about anything about the moment of inertia or angular acceleration.Anyways,The plank will rotate,Am I right?
Then where should I apply a force so the plank will only move straight without rotating?On the center of Mass?The motion of the plank will be a combination of the translation of the center of mass plus rotation about the center of mass. It will rotate as well as translate.
Yes, at the center of mass.Then where should I apply a force so the plank will only move straight without rotating?On the center of Mass?
When you remove the force, the center of mass will continue moving in a straight line at constant speed. And the plank will continue to rotate about its center of mass with a constant angular velocity.When I apply the force on the sides it will rotate and translate,What will happen if I remove the force.Will the plank keep rotating and translating or Move in a constant velocity in a straight line?
