ROTATIONAL MOTION Quiz

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

• F = ma for each particle only
• dP/dt = 0 always
• F = mv^2/r
• dP/dt = F_ext

• P = M/V
• P = M + V
• P = V/M
• P = MV

• Product of total mass and velocity of any particle
• Scalar sum of all individual momenta
• Average of all individual momenta
• Vector sum of the momenta of all individual particles

• The momentum increases indefinitely
• The momentum decreases to zero
• The momentum changes direction randomly
• The total linear momentum remains constant
