ROTATIONAL MOTION

What is the angular momentum of a particle at a fixed distance moving perpendicular to r?

• Zero
• Minimum
• Maximum
• r

What happens to angular momentum if no external torque acts?

• It increases
• It decreases
• It remains constant
• It becomes zero

What is the relationship between torque and angular momentum?

• τ = l/t
• τ = dl/dt
• τ = l × r
• τ = d²l/dt²

What is the effect of increasing r on angular momentum, keeping p constant?

• It decreases
• It increases
• No effect
• It becomes zero

How is angular momentum conserved?

• When net force is zero
• When net external torque is zero
• When velocity is constant
• When acceleration is zero
