(A) Moment of a Force and Equilibrium

1.1. Translational and Rotational Motions

(1) Linear or Translational Motion

When a force acts on a stationary rigid body which is free to move, the body starts moving in a straight path in the direction of the applied force.

This is called linear or translational motion. ​
