Final answer:
Objects with more kinetic energy can cause more deformation during a collision due to the larger impact force associated with the increased energy of motion.
Step-by-step explanation:
When objects in a system have more kinetic energy, it means they can produce more deformation in a collision. Kinetic energy, which is the energy an object possesses due to its motion, contributes to the ability of an object to do work or cause a change. In the context of collisions, increased kinetic energy can lead to a greater impact force, which might result in more deformation of the objects involved.
For example, a speeding bullet has a significant amount of kinetic energy and can cause considerable deformation upon impact. This principle is also why a heavy truck and a small car, traveling at the same speed, would result in the truck having more kinetic energy due to its greater mass, and thus could potentially cause greater deformation in a collision.
