Projectile and Target before collision

Inelastic --------- ElasticInelastic: projectile embeds itself inside the target. Energy is lost in the collision.
Elastic: no energy is lost in the collision. Projectile bounces off the target transfering some of its momentum

ProjectileCharacteristic of the projectile. Speed and mass.

Projectile Quick SelectPresets speed and mass of several projectiles.

Projectile Speed [m/s]Muzzle velocity.

Projectile Mass [g]Projectile mass.

Projectile Energy [J]Damage is proportional to energy. Energy scales linearly with mass and quadratically with speed.

TargetTarget.

Target Quick SelectPresets of targets.

Target Speed [m/s]Target is fixed compared to projectile.

Target Mass [g]Target mass. Best transfer of kinetic energy happens when projectile and target have the same mass.

Target Energy [J]Target kinetic energy before collision.

Projectile and Target after collisionxxx

ProjectileProjectile

Projectile Speed [m/s]Speed of the projectile after the collision. A negative number means the projectile bounced back.

Projectile Energy [J]Energy of the projectile after collision. Energy is lost as heat due to deformation and is transferred to target as kinetic energy.

Targetxxx

Target Speed [m/s]kinetic energy absorbed by the target puts it in motion.

Target Energy [J]kinetic energy absorbed by the target

---

Total Energyxxx

Total Energy Before Collision [J]Total kinetic energy held inside projectile and target before collision

Energy Lost [J]Energy dissipated as heat during the collision due to deformation of either target or projectile.

Energy Transferred [J]Kinetic energy transferred from projectile to target.

Total Energy After Collision [J]Total kinetic energy held inside projectile and target after collision

Energy Lost [%]Fraction of total energy dissipated as heat during the collision.

Energy Transferred [%]Fraction of energy transferred from projectile to target.
