Suppose that two objects collide. Which of the following things is not the same both before and after the collision?
A)the total temperature of the objects
B)the total angular momentum of the objects
C)the total momentum of the objects
D)the total energy of the objects

Quizplus · Accepted Answer

Temperature is a measure of the average kinetic energy of the particles in an object. In a collision, the total temperature of the objects is not a conserved quantity and it can change due to the conversion of some of the kinetic energy into other forms (such as sound, deformation or heat). On the other hand, momentum, energy and angular momentum are all conserved quantities in a collision, meaning their total values before and after the collision must be the same.
