What is Energy?04:10

What is Energy?

59.2K
The universe is composed of matter in different forms, and all forms of matter contain energy.  The different forms of energy on Earth originate from the Sun — the ultimate energy source. Plants capture light energy from the Sun, and, via the process of photosynthesis, convert it into chemical energy. This stored energy from plants can be harnessed in many ways. For example, eating plant products as food provides energy for our body to function, and burning wood or coal (fossilized...

Free Energy

52.1K
Free energy—abbreviated as G for the scientist Gibbs who discovered it—is a measurement of useful energy that can be extracted from a reaction to do work. It is the energy in a chemical reaction that is available after entropy is accounted for. Reactions that take in energy are considered endergonic and reactions that release energy are exergonic. Plants carry out endergonic reactions by taking in sunlight and carbon dioxide to produce glucose and oxygen. Animals, in turn, break...

Free Energy Changes for Nonstandard States

13.6K
The free energy change for a process taking place with reactants and products present under nonstandard conditions (pressures other than 1 bar; concentrations other than 1 M) is related to the standard free energy change according to this equation:

Potential Energy00:52

Potential Energy

42.7K
The energy stored by a structure and location of matter in space is called potential energy. For instance, raising a kettlebell changes its spatial location and increases its potential energy. Similarly, a stretched rubber band contains potential energy which, under certain conditions, can be converted into other forms of energy, such as kinetic energy.
Chemical bonds that form attractive forces between atoms also contain potential energy, called chemical energy. When a chemical reaction...

Energy Budgets00:51

Energy Budgets

10.9K
Organisms must balance energy intake with the energy required for growth, maintenance and reproduction. These trade-offs result in a variety of survivorship and reproductive strategies, including semelparity and iteroparity. Semelparous species, like annual plants, have only one reproductive episode in their lifetimes and consequently have short lifespans. Iteroparous species, by contrast, have many reproductive events during their lifetimes but have relatively few offspring. These two...

Area of Science:

  • Orthopedic Surgery
  • Traumatology
  • Geriatric Medicine

Background:

  • Bilateral posterior hip dislocation is a rare injury, often associated with high-energy trauma.
  • Low-energy mechanisms are infrequently reported, particularly in the absence of pre-existing hip pathology.

Observation:

  • An 88-year-old male presented with bilateral posterior hip dislocation following a low-energy fall.
  • Associated findings included right peroneal nerve palsy.
  • Closed reduction was successfully performed in the emergency department, with hip stability confirmed under anesthesia.

Findings:

  • This represents a previously undescribed case of low-energy, bilateral posterior hip dislocation in the medical literature.
  • The injury occurred in an elderly patient, highlighting potential vulnerability to falls.

Implications:

  • Prompt diagnosis and reduction of hip dislocations are critical for favorable outcomes.
  • Elderly patients with hip dislocations face significant risks of morbidity and mortality, underscoring the need for careful management.
  • This case expands the understanding of potential etiologies for bilateral hip dislocations.
