ROTATIONAL MOTION Quiz

• By integrating velocity
• By multiplying velocity with mass
• By taking the time derivative of the centre of mass velocity
• By squaring the velocity

• Mass of the first particle
• Reduced mass of the system
• Total mass of the system
• Average mass of particles

• Because they are negligible
• Because they act perpendicular to motion
• Because they cancel in pairs
• Because they are variable

• It gives the total kinetic energy
• It gives the angular momentum
• It gives the position vector of the centre of mass
• It gives the torque on the system

• d/dt = A V
• d/dt = F p
• d/dt = V r
• d/dt = V R
