Kinematics Equations Force of Gravity Between Two Objects Units of G = N∗m²/kg² Brainpower Read More 0:13 / 0:15 Kinetic Friction Static Friction Uniform Circular Motion - Velocity Velocity vector is constantly changing and is tangential to the circle of motion Centripetal Acceleration The acceleration vector always points toward the center of the circle and constantly changes direction as the object moves. Centripetal Force Torque θ...

Energy is transferred between stores - Thermal, kinetic, gravitational potential, elastic potential, chemical, magnetic, electrostatic, nuclear Energy is transferred... - Mechanically (by a force doing work), electrically (work done by moving charges), by heating or by radiation (like light or sound) When a system changes, energy is transferred - It can be transferred into or away from the system, between objects in the system or between different types of energy stores. Closed systems are...

ATLS EXAM (QUESTIONS AND ANSWERS A+ GRADED 100% VERIFIED) True or false? Although the mechanism of injury may be similar to those for the younger population, data shows increased mortality with similar severity of injury in older adults. ANS: True In the elderly population, what is decreased physiological reserve? ANS: aging is characterized by impaired adaptive and homeostatic mechanisms that caused an increased susceptibility to the stress of injury. Insults tolerated by the younge...

Types of body damage Direct; Indirect; Minor; Major Direct Damage Results in direct contact with an object. Holes, tears, gouges, and scratches are typical. Generally 10% of collisions result in direct damage Indirect Damage Results from direct damage. Impact cause another panel to lift, buckle, or tear. Rear end collision may result in damage near middle of car Minor Damage Involves little repair time and skill to complete Major Damage Requires more: time, s...
