ROTATIONAL MOTION Quiz

• It accelerates randomly
• It moves in a circular path
• It moves with constant velocity or remains at rest
• It comes to rest immediately

• They dominate the motion
• They cause rotational motion only
• They cancel out due to Newton’s third law
• They increase the kinetic energy

• M = A F_int
• M = A F_total
• M = A F_ext
• F = dp/dt

• The geometric centre of the body
• The heaviest point in the system
• The point where the entire mass of the system can be assumed to be concentrated for translational motion
• The point with zero velocity
