ROTATIONAL MOTION

How can angular momentum be expressed using perpendicular distance?

• l = r⊥ / p
• l = r⊥ p
• l = p / r⊥
• l = r + p

Under what condition is angular momentum zero?

• When velocity is maximum
• When mass is zero
• When particle is at origin
• When θ = 90°

What is the magnitude of angular momentum in terms of θ?

• l = r p cosθ
• l = r p tanθ
• l = r p sinθ
• l = r² p

How is angular momentum of a particle defined with respect to the origin?

• l = r + p
• l = r × p
• l = r · p
• l = p × r

What is the rotational analogue of linear momentum?

• Force
• Torque
• Angular momentum
• Kinetic energy
