Force

33.4K
Forces affect every moment of our life. Our bodies are held to the Earth by force, and they are held together by the forces of charged particles. When we open a door, walk down a street, lift a fork, or touch a baby's face, we are applying force. Our body's atoms are held together by electrical forces, and the core of an atom, called the nucleus, is held together by the strongest force known to us—nuclear force.
The study of motion is called kinematics, but kinematics only...

Introduction to force

Consider water flowing from a nozzle to a turbine vane. As the water hits the turbine vane, it exerts a force that causes it to move along the flow of direction. Force is an impact that changes an object's motion, shape, or orientation. Forces can be caused by physical contact, such as a push or pull, or through non-contact interactions, such as magnetic or gravitational forces. Force is a vector quantity with both magnitude and direction, and is measured in newtons (N) in the SI unit...

Parenting Styles

Diana Baumrind's four parenting styles — authoritarian, authoritative, neglectful, and permissive — each influence children's socio-emotional development differently.
Authoritarian Parenting
This style is strict and controlling, with little room for open dialogue. Authoritarian parents demand obedience and often enforce rules with minimal warmth. Children raised this way may lack social skills and initiative, usually comparing themselves to others unfavorably.

Milgram's Obedience to Authority

7.5K
Obedience to authority is classically demonstrated in a more famous series of social psychology experiments performed by Stanley Milgram. He was a social psychology professor at Yale who was influenced by the trial of Adolf Eichmann, a Nazi war criminal. Eichmann’s defense for the atrocities he committed was that he was “just following orders.”

Force Classification01:22

Force Classification

2.5K
Forces play a crucial role in the study of physics and engineering. They are essential in describing the motion, behavior, and equilibrium of objects in the physical world. Forces can be classified based on their origin, type, and direction of action.
Contact and non-contact forces are two of the most widely used categories of forces. As the name suggests, contact forces require physical contact between two objects to act upon each other. Examples of contact forces include frictional,...

Drug Dosing: Infants and Children01:29

Drug Dosing: Infants and Children

615
Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Area of Science:

  • Child Development and Protection
  • Criminology and Law
  • Public Health Policy

Background:

  • Canada permits 'reasonable' physical punishment of children, unlike 52 other countries.
  • The Supreme Court of Canada set legal limits on corrective force in 2004.

Purpose of the Study:

  • To evaluate the effectiveness of the Supreme Court's 2004 limits in protecting children from physical maltreatment.
  • To determine if substantiated child physical abuse cases exceed the established legal boundaries.

Main Methods:

  • Operationalized the Supreme Court's limits on physical punishment.
  • Applied these limits to a provincial sample of substantiated child physical maltreatment cases.

Main Results:

  • Most substantiated physical abuse cases fell within the court's defined limits.
  • In over 25% of cases, none of the court's limits were exceeded.
  • The prevalence of spanking in the home was the strongest predictor of substantiated abuse reports.

Conclusions:

  • The current legal limits on physical punishment in Canada are insufficient to protect children.
  • Abolishing physical punishment entirely would offer greater child protection than the existing legal framework.
  • The findings support policy changes towards the complete prohibition of corporal punishment.
