which at Earth's surface has a value of 9.8 meters per second squared (9.8 m/s2).Tension, elasticity, frictionand the so-callednormal forceare forces that act on solids; buoyancy, lift, thrust and drag are forces uniquely associated with fluids (liquids and gases). ...
During the underwater phase of the swimming start drag forces are constantly acting to slow the swimmer down. The current study aimed to quantify total drag force as well as the specific contribution of wave drag during the underwater phase of the swimming star...
Urbanization and climate change are contributing to severe flooding globally, damaging infrastructure, disrupting economies, and undermining human well-being. Approaches to make cities more resilient to floods are emerging, notably with the design of flood-resilient structures, but relatively little is kno...
Pricing beauty and cosmetics products depends on your target market. To calculate a profitable price you need to know the cost of your raw materials plus packaging and overhead. Multiply that by 5 or 6 to get a good idea for the retail price. If you want to sell wholesale, divide your ...

Typically, flight engineers are fully trained pilots, but on an ordinary trip, they don't fly the plane. Instead, they monitor the airplane's instruments and calculate figures such as ideal takeoff and landing speed, power settings and fuel management. In newer airliners, most of this work ...
To calculate the amount of power a turbine can actually generate from the wind, you need to know the wind speed at the turbine site and the turbine power rating. Most large turbines produce their maximum power at wind speeds around 15 meters per second (33 mph). Considering steady wind spe...

Lift Force Equation Objects flying through the air have to deal with the force of air exerted against themselves. When the object moves forward through the air, the drag force is the part of the force that acts parallel to the flow of motion. Lift, by contrast, is the part of the force...
