Level 4.0 Question : Provide an example of a collision with damage from your own life, then explain how the concept of kinetic energy relates to the damage in your collision. What would happen in your collision if there was more KE vs less KE? What would happen if one of the subsystems had more mass? What would happens if one of your subsystems had more speed?
