Behavioral momentum is a theory in quantitative analysis of behavior and is a behavioral metaphor based on physical momentum.It describes the general relation between resistance to change (persistence of behavior) and the rate of reinforcement obtained in a given situation.
In Newtonian mechanics, momentum (pl.: momenta or momentums; more specifically linear momentum or translational momentum) is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction.
The table usually lists only one name and symbol that is most commonly used. The final column lists some special properties that some of the quantities have, such as their scaling behavior (i.e. whether the quantity is intensive or extensive ), their transformation properties (i.e. whether the quantity is a scalar , vector , matrix or tensor ...
The momentum effect raises a further important issue. If markets are rational, as the efficient-market hypothesis assumed, then they will allocate capital to its most productive uses. But the momentum effect suggests that an irrationality might be at work; investors could be buying shares (and commodities) just because they have risen in price.
As with many areas of cognitive psychology, theories can focus on bottom-up or top-down aspects of the task. Bottom-up theories of representational momentum highlight the role of eye movements and stimulus presentation, [5] [6] while top-down theories highlight the role of the observer's experience and expectations regarding the presented event ...
All dynamical variables can be derived from position q, momentum p, and time t, and written as a function of these: A = A(q, p, t). If A ( q , p , t ) and B ( q , p , t ) are two scalar valued dynamical variables, the Poisson bracket is defined by the generalized coordinates and momenta:
An adjustable-rate mortgage — commonly called an ARM — is a type of home loan with a variable rate. Unlike a fixed-rate mortgage, which locks in an interest rate and predictable payments that ...
The moment of force, or torque, is a first moment: =, or, more generally, .; Similarly, angular momentum is the 1st moment of momentum: =.Momentum itself is not a moment.; The electric dipole moment is also a 1st moment: = for two opposite point charges or () for a distributed charge with charge density ().
