ROTATIONAL MOTION Quiz

• Work is inversely proportional
• Work is independent
• Work is proportional to the angle turned for constant torque
• Work depends on speed

• Torque is maximum
• Torque increases
• Net torque is zero
• Torque is infinite

• Radial
• Axial
• Tangential to the circular path
• Perpendicular to the axis

• It increases torque
• It makes forces zero
• It ensures all torques act on the same rotating system with common dθ
• It eliminates work

• One is scalar, other vector
• Rotational work is always zero
• Rotational work depends on angle, while linear work depends on linear distance
• They have different units
