You can balance a seesaw when the torques are balanced in equilibrium â that is, when the sum of the torques is zero and the torques on one side of the fulcrum are equal and opposite to the torques on the other side. For this activity the force is just the weight of the mass given by w = mg.
Likewise, as elevation increases, there is less overlying atmospheric mass, so that atmospheric pressure decreases with increasing elevation.he boiling point is the temperature at which the vapor pressure is equal to the atmospheric pressure around the water. Because of this, the boiling point of water is lower at lower pressure and higher at higher pressure.
CHANGES IN ATMOSPHERIC PRESSURE. METEOROLOGIST JEFF HABY. One of the earliest forecasting tools was the use of atmospheric pressure. Soon, after the invention of the barometer, it was found that there were natural fluctuations in air pressure even if the barometer was kept at the same elevation. During times of stormy weather the barometric pressure would tend to be lower.
