TNCC COMPLETE QUESTIONS AND CORRECT ANSWERS LATEST UPDATE 2024 The consequences of mechanical energy are directly related to __________ energy Kinetic Kinetic Energy (KE) is equal to 1/2 the mass multiplied by the velocity squared In other words: when mass is doubled, energy is doubled; when velocity is doubled, energy is quadrupled Kinetic Energy formula KE=1/2mv^2 Differentiate between internal and external forces of energy transfer in the context or trauma. External forces are how energy can impact the body (e.g., deceleration, acceleration, compression). Internal forces represent the ability of the body to withstand external forces. How do internal forces protect the body from injury? - Compression strength: ability of tissue to resist crush injury or force - Tensile strength: ability to resist being pulled apart when stretched - Shear strength: ability to resist a force applied parallel to the tissue List four main types of traumatic injury - Blunt trauma - Penetrating trauma - Thermal trauma - Blast trauma Examples of blunt trauma Falls MVA Vehicle vs. pedestrian collisions Assaults *Can result from broad energy impacts across large surface areas and involve energy transfer causing deceleration or acceleration *Greater distance of transfer diminishes deleterious impacts, and the more focused the impact, the greater the damage Deceleration injuries Occurs as energy is dispersed from the moving object
