Free-falling Bodies: Example01:05

Free-falling Bodies: Example

31.5K
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: Introduction

11.6K
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...

Relative Risk01:12

Relative Risk

2.0K
Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

13.3K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Design Example: Analyzing Capacity Contours for Flood Risk Assessment01:17

Design Example: Analyzing Capacity Contours for Flood Risk Assessment

292
Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...

Uncertainty in Measurement: Accuracy and Precision03:37

Uncertainty in Measurement: Accuracy and Precision

100.5K
Scientists typically make repeated measurements of a quantity to ensure the quality of their findings and to evaluate both the precision and the accuracy of their results. Measurements are said to be precise if they yield very similar results when repeated in the same manner. A measurement is considered accurate if it yields a result that is very close to the true or the accepted value. Precise values agree with each other; accurate values agree with a true value.

Area of Science:

  • Gerontology
  • Biomedical Engineering
  • Mobile Health

Background:

  • Postural sway and delayed motion reaction time are indicators of increased fall risk in older adults.
  • Objective, accessible tools are needed to predict falls and guide interventions in community-dwelling seniors.

Purpose of the Study:

  • To evaluate the feasibility of the Senior Sway mobile application for assessing fall risk.
  • To examine the association between Senior Sway metrics and established fall risk indicators.

Main Methods:

  • Recruited community-dwelling adults aged 62 years and older.
  • Assessed Senior Sway application feasibility through enrollment, user satisfaction, and assessment duration.
  • Utilized descriptive and bivariate statistics to analyze the association with fall risk measures.

Main Results:

  • The Senior Sway application was found to be feasible, with 91% user satisfaction and appropriate assessment time.
  • Senior Sway scores demonstrated significant associations with the 30-second sit-to-stand test and Timed Up and Go test.
  • The application effectively measures postural sway and motor reaction time.

Conclusions:

  • The Senior Sway mobile application is a promising, feasible tool for identifying older adults at elevated risk of falls.
  • Further research is warranted to validate its utility in clinical settings and for guiding rehabilitation needs.
