WebThe distance between the centers of mass of two objects affects the gravitational force between them, so the force of gravity on an object is smaller at the equator compared to the poles. This effect alone causes the gravitational acceleration to be about 0.18% less at the equator than at the poles. WebThe term "standard sea level" is used to indicate that values of properties are to be taken to be the same as those standard at sea level, and is done to define values for use in general calculations. Atmospheric properties[edit] At SSL some atmospheric properties are:[2] Pressure, P= 101.325 kPa⇔ 2116.2 lbf/ft2⇔ 14.696 lbf/in2⇔ 29.92 inHg

WebNov 7, 2024 · An atmosphere (atm) is a unit of measurement equal to the average air pressure at sea level at a temperature of 15 degrees Celsius (59 degrees Fahrenheit). One atmosphere is 1,013 millibars, or 760 millimeters (29.92 inches) of mercury. Atmospheric pressure drops as altitude increases. WebExpert Answer. The gravitational constant g is 9.807 m/s2 at sea level, but it decreases as you go up in elevation. A useful equation for this decrease in g is g= a - bz, where z is the elevation above sea level, a = 9.807 m/s2, and b = 3.32 x 10-6 1/82. An astronaut “weighs” 80.0 kg at sea level.
WebWhen you have an object submerged in a fluid, the pressure at the bottom of the object is larger than the pressure at the top of the object. Since there is a pressure difference, there is also a force, in this case pointing upwards. This force is what we call the buoyant force.
