Free-falling Bodies: Example01:05

Free-falling Bodies: Example

An object falling without any air resistance under the influence of gravitational force is said to be in free-fall. For free-falling bodies, the acceleration due to gravity is constant, irrespective of their mass. Free-fall is experienced not only by objects falling downward, but also by all objects whose motion is influenced by gravitational force alone. The dynamics of free-fall motion can be calculated using kinematic equations of motion, since free-fall acceleration is constant.

Free-falling Bodies: Introduction01:07

Free-falling Bodies: Introduction

All objects, neglecting air resistance, fall with the same acceleration towards the Earth's center due to the force exerted by the Earth's gravity. This experimentally determined fact is unexpected because we are so accustomed to the effects of air resistance and friction that we expect light objects to fall slower than heavier ones. People believed that a heavier object had a greater acceleration when falling until Galileo Galilei (1564–1642) proved otherwise. We now know this is not the case.
Rolling With Slipping01:14

Rolling With Slipping

Rolling with slipping is a physical phenomenon that occurs when a rolling object experiences both rotational and linear motion but also experiences frictional forces that cause slipping. This phenomenon can occur in various situations, such as when a tire rolls on a wet road or a ball rolls on a rough surface.
An object's rolling motion is characterized by its rotation around its axis, while linear motion refers to the object's translational motion along a surface. Frictional forces can affect...
Types of Collisions - II01:19

Types of Collisions - II

When two or more objects collide with each other, they can stick together to form one single composite object (after collision). The total mass of the object after the collision is the sum of the masses of the original objects, and it moves with a velocity dictated by the conservation of momentum. Although the system's total momentum remains constant, the kinetic energy decreases, and thus such a collision is an inelastic collision. Most of the collisions between objects in daily life are...
Fractures: Bone Repair01:27

Fractures: Bone Repair

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
Types Of Collisions - I01:04

Types Of Collisions - I

When two objects come in direct contact with each other, it is called a collision. During a collision, two or more objects exert forces on each other in a relatively short amount of time. A collision can be categorized as either an elastic or inelastic collision. If two or more objects approach each other, collide and then bounce off, moving away from each other with the same relative speed at which they approached each other, the total kinetic energy of the system is said to be conserved. This...

Area of Science:

  • Nursing
  • Patient Safety
  • Healthcare Management

Background:

  • Patient falls pose significant risks, leading to morbidity and mortality.
  • Fatalities from falls have increased, with projected costs exceeding $40 billion annually.
  • Healthcare facilities face substantial risks from patient falls.

Purpose of the Study:

  • To implement and evaluate the Helping Hands program, a nurse-directed falls prevention strategy.
  • To foster a hospital-wide culture of safety and reduce fall-related harm.
  • To assess the effectiveness of nursing interventions in falls prevention.

Main Methods:

  • Utilized the Johns Hopkins Fall Risk Assessment Tool for nursing assessment.
  • Implemented communication mechanisms, reporting processes, and change champion roles.
  • Engaged patients and families, increased public awareness, and employed nursing performance improvement analysts.

Main Results:

  • Over 3 years, 65% of patients assessed were at risk of falling.
  • Total falls decreased by 16.6% within the study period.
  • Severe falls represented a minimal 0.009% of all falls.

Conclusions:

  • Nursing engagement is crucial for developing a hospital-wide safety culture.
  • The Helping Hands program effectively reduced patient falls and associated harm.
  • Data suggest a positive impact of nursing-led initiatives on patient safety outcomes.
