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.
The pressure at any location on the Earth, caused by the weight of the column of air above it. At sea level, atmospheric pressure has an average value of one atmosphere and gradually decreases as altitude increases. Also called barometric pressure.
