Question

A force produces translational motion:

• A. When the body is free to move and applied force pass through the rotation axis
• B. When the body is hindered to move
• C. When the body is rigidly fixed
• D. When the body is free to move and applied force does not pass through the rotation axis

Answer 1

The correct option is A When the body is free to move and applied force pass through the rotation axis

For the application of translational motion, the body must be free to move and after applying force, all the particles in that body move with the same velocity. So applied force must pass through the rotation axis otherwise force can rotate the body.
