For example, a big … Nettet21. mar. 2024 · Water molecules leaving a surface have a momentum directed away from the surface. This momentum of the added molecules results in an increase in pressure of the air mass. The air expands against the surrounding atmosphere increasing the volume. The collisions with other molecules push them away until pressures [almost] equalize.

"Nettet2. okt. 2024 · So when an object is submerged in water, there is an upward force due to the pressure at the bottom of the object - it's h ρ g where h is the depth to the bottom of the object ( h 2) and ρ is density. The pressure at the top is less, h ρ g again but this time with a lower value of h, say h 1. " - Moving air and water can push objects

NettetThe force pushing the object upward is called the There are a number of factors related to whether an object will float or sink in a fluid. Objects placed in a fluid displace their volume of the fluid. If the density of the object is less than the density of the fluid, the object will float. NettetWhen the surface of an object tries to move through these gases and molecules, it causes them to push back in the opposite direction. This slows the object down.
