ROTATIONAL MOTION Quiz

• Two forces acting in the same direction
• Two equal and opposite forces acting at the same point
• Two unequal forces acting at different points
• Two equal and opposite forces acting at different points on a body

• A couple has more mass
• A couple moves faster
• A couple produces torque without net force, while a single force produces both
• A single force produces no torque

• Rotation occurs
• Translation occurs
• No motion occurs
• Oscillation occurs

• It changes the mass
• It affects only translational motion
• It determines the sense (clockwise or counterclockwise) of the torque produced
• It changes the length

• It increases force
• It has no significance
• Because it is where gravity acts
• Because it is equidistant from symmetric force points, simplifying calculations
