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.
Atmospheric pressure is not always the same. If a low pressure system or a high pressure system is passing over your house, that will change the atmospheric pressure. Air pressure also changes as you go up! The air pressure in Earth's atmosphere is pretty strong when you are near sea level. When you go higher up, in an airplane or to the top of a mountain, there is less pressure. Temperature also affects atmospheric pressure. Warmer temperatures will make atmospheric pressure go up.
