ROTATIONAL MOTION Quiz

• v
• 2v
• v/2
• Zero

• By eliminating rotation
• By making the body massless
• By separating translational motion from rotational motion
• By reducing size

• Only external forces are included
• Internal forces dominate
• The product of total mass and CM acceleration equals the vector sum of all forces on all particles
• The system is in equilibrium

• With increasing speed
• With decreasing speed
• With constant velocity
• In a circular path

• It makes the velocity zero
• It eliminates gravity
• It allows the mass to be factored out during differentiation
• It reduces the number of particles
