Assume there is a revolute joint, a torque (just caused by a couple, not by a force) can make it rotate around the axis. why there are two parasitic velocities along x-axis and y-axis?

The force is the reason for the acceleration based on Newton's second lawm, not the velocity.

thank you.

hello, I have a question, what is the reason for the velocity of a rigid body? I know the force is the reason for movement status changing of a rigid body. And also this can be said, the forces and the movements are reciprocal to each other. now, what is the reciprocal part of the...
