ROTATIONAL MOTION Quiz

• τ = Σ (rᵢ · Fᵢ)
• τ = Σ (Fᵢ × rᵢ)
• τ = Σ (rᵢ + Fᵢ)
• τ = Σ (rᵢ × Fᵢ)

• L = Σ (rᵢ · pᵢ)
• L = Σ (pᵢ × rᵢ)
• L = Σ (rᵢ + pᵢ)
• L = Σ (rᵢ × pᵢ)

• It increases continuously
• It decreases to zero
• It changes direction randomly
• It remains constant

• V = P × M
• V = M/P
• V = P²/M
• V = P/M

• The geometric center regardless of mass
• The heaviest particle's location
• The midpoint between two extreme particles
• As the point whose position vector is the mass-weighted average of individual position vectors
