ROTATIONAL MOTION Quiz

• It increases torque
• It causes imbalance
• It ensures equal lever arms for symmetrically applied forces, simplifying torque cancellation
• It has no effect

• The net force increases
• The torque doubles
• The rotation becomes faster
• The net torque becomes zero

• It increases linear speed
• It reduces mass
• It produces a turning effect without causing translational motion
• It generates heat

• Because it moves too fast
• Because it has infinite mass
• Because it is always accelerating
• Because a particle has no dimensions and cannot rotate about an axis

• Only x-component must be zero
• Only y-component must be zero
• The sum of force components along any two perpendicular axes must be zero
• Torque must be zero
