Children of Orion
Kinetic damage is from the form of a “solid” impacting and the force at which the “solid” is travailing at is transferred to the target in inertial damage or Kinetic force.
Slashing damage is a bit different though it is a form of special Kinetic damage from edged weapons which can range from knives to nano-swords. This damage is broke out to recognize weapon combat which cuts instead of uses blunt force trauma such as projectiles. One example of needed differential of damage is the use of Inertial Screens; Combat with Kinetic damage can be mitigated by Inertial Screens when worn personally but when in melee combat with edged weapons a fighting skill can allow the blade to penetrate the Screen where as any other form of Kinetic damage is deflected due to the nature of Screens.
