Question

1. what is not conserved in an inelastic collision?

potential energy
kinetic energy
momentum
acceleration

Explanation:

In inelastic collisions, momentum is always conserved. Potential energy is not the key quantity tracked here, and acceleration is a variable that changes during collisions but is not a conserved quantity in the context of collision conservation laws. Kinetic energy is not conserved because some of it is converted to other forms (like heat, sound, or deformation energy) during the inelastic collision.

Answer:

B. kinetic energy
