Imagine that you’re observing a collision. which action would allow you to determine whether the collision is inelastic? measure the force of impact. observe whether the colliding objects change their shape. measure the acceleration of the colliding objects. measure the mass of the colliding objects.

The action that would allow you to determine whether the collision is inelastic when a collision occurred is when you observed that the colliding objects change their shape. The correct answer would be the second option. Inelastic collision is defined as a collision wherein the kinetic energy is not conserved because of internal friction. The kinetic energy in this collision becomes a vibrational energy which results in a heating effect and the bodies are deformed.
