In which of these collisions would angular momentum NOT be conserved?
A) A collision in which linear momentum is also conserved
B) A collision which is perfectly inelastic
C) A collision which is perfectly elastic
D) A collision with a net external torque
D) A collision with a net external torque.
The law of conservation of angular momentum states that when no external torque acts on an object, no change of angular momentum will occur.
