  1. MSTC Physics 2 Chapter 8 Sections 1-2

  2. Translational vs Rotational Motion • Translational motion is produced by a force through an object’s center • Rotational motion is produced by a force applied away from the center

  3. Torque • Force that produces rotation • Torque = force x lever arm Τ = Fl where Τ = tau [Τ] = Nm • If force causes to rotate counterclockwise is positive torque

  4. Torque cont’d. • Line of action – line along which force acts • Lever arm – perpendicular distance from rotational axis to line of action • Torque depends on amount of force, how applied, and where applied
