When a rigid body, such as a disk, is floating in space and a force is applied off-center, it will both rotate and move linearly. The center of mass of the disk is free to move, leading to a combination of translational and rotational motion. This phenomenon occurs due to the principles of dynamics, specifically the application of torque and linear force. The discussion confirms that both movements are inevitable when force is applied outside the center of mass.
PREREQUISITESPhysics students, mechanical engineers, and anyone interested in the principles of motion and dynamics of rigid bodies.
freephoton said:if a rigid body, let's say a disk,is floating in space and we exert a force outside its center of mass will it rotate or just start a linear move? its center of mass is free to move.sorry if my English are not so good.I hope that you understood the question
