ROTATIONAL MOTION

What determines the plane in which torque and angular momentum act?

• Plane of F and τ
• Plane of L and ω
• Plane of r and v
• Plane of gravity and motion

Is angular momentum a scalar or vector quantity?

• Dimensionless
• Pseudoscalar

What happens to angular momentum if external torque is absent?

• It decreases gradually
• It becomes zero
• It remains conserved
• It reverses direction

What is the net torque in rotational equilibrium?

• Maximum
• Minimum
• Infinite
• Zero

What is the net force in translational equilibrium?

• Maximum
• Zero
• Equal to weight
• Balanced by friction
