The force on the mass is equal to the vector sum of the spring force and the kinetic frictional force. When the velocity changes sign (at the maximum and minimum displacements), the magnitude of the force on the mass changes by twice the magnitude of the frictional force, because the spring force is continuous and the frictional force reverses ...
In the Penrose process, a body divides in two, with one half gaining negative energy and falling in, while the other half gains an equal amount of positive energy and escapes. This is proposed as the mechanism by which the intense radiation emitted by quasars is generated.
It is the underlying life principle inaugurating all aspects of life and behavior, a self-preserving force. A sense of entropy and the eternal return, which are related, is always indissociable from the will to power. The eternal return of all memory initiated by the will to power is an entropic force again inherent to all life.
A new study from Michigan State University says that there's a physical, biological difference in the brains of optimists and pessimists. The study took 71 female participants and pre-screened ...
Melancholy by Domenico Fetti (1612). Death, suffering and meaninglessness are the main themes of philosophical pessimism. Philosophical pessimism is a philosophical tradition which argues that life is not worth living and that non-existence is preferable to existence.
A body force is simply a type of force, and so it has the same dimensions as force, [M][L][T] −2. However, it is often convenient to talk about a body force in terms of either the force per unit volume or the force per unit mass. If the force per unit volume is of interest, it is referred to as the force density throughout the system.
The concept of allostasis, maintaining stability through change, is a fundamental process through which organisms actively adjust to both predictable and unpredictable events... Allostatic load refers to the cumulative cost to the body of allostasis, with allostatic overload... being a state in which serious pathophysiology can occur...
Inertia is the natural tendency of objects in motion to stay in motion and objects at rest to stay at rest, unless a force causes the velocity to change. It is one of the fundamental principles in classical physics, and described by Isaac Newton in his first law of motion (also known as The Principle of Inertia). [1]
