In compressible fluid dynamics, impact pressure (dynamic pressure) is the difference between total pressure (also known as pitot pressure or stagnation pressure) and static pressure. [ 1 ] [ 2 ] In aerodynamics notation, this quantity is denoted as q c {\displaystyle q_{c}} or Q c {\displaystyle Q_{c}} .
Road traffic accidents usually involve impact loading, such as when a car hits a traffic bollard, water hydrant or tree, the damage being localized to the impact zone. When vehicles collide, the damage increases with the relative velocity of the vehicles, the damage increasing as the square of the velocity since it is the impact kinetic energy ...
In fluid dynamics, dynamic pressure (denoted by q or Q and sometimes called velocity pressure) is the quantity defined by: [1] = where (in SI units): q is the dynamic pressure in pascals (i.e., N/m 2, ρ (Greek letter rho) is the fluid mass density (e.g. in kg/m 3), and; u is the flow speed in m/s.
Dynamic apnea is a discipline of competitive freediving, also known as competitive apnea. Dynamic apnea covers two of the eight competitive freediving categories recognised by the AIDA International (International Association for Development of Apnea): dynamic with fins ( DYN ) and dynamic without fins ( DNF ).

The CEO of investment firm Azoria lobbied DOGE figurehead Elon Musk to have the department issue stimulus checks from some of the claimed $55 billion in savings.
Besides these metabolic effects, GLP-1 drugs also appear to have an impact on brain health and mental health. Since some studies show that GLP-1 drugs may have an impact on addictive behaviors, ...
The Trump administration has ordered the Consumer Financial Protection Bureau to stop nearly all its work, effectively shutting down an agency that was created to protect consumers after the 2008 ...
These dynamic loads may involve considerations such as impact, momentum, vibration, slosh dynamics of fluids and material fatigue. Live loads, sometimes also referred to as probabilistic loads, include all the forces that are variable within the object's normal operation cycle not including construction or environmental loads.
