Moving air and water can push objects

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. Nettet23. jan. 2024 · Light carries momentum that can push on an object, but it can also move an object through thermal forces. A new experiment combines both of these effects to manipulate a tiny gold plate that can slide along a tapered optical fiber. The momentum-transfer and thermal forces act in opposite directions, allowing the plate to be driven …

Nettet28. nov. 2014 · A: When objects are placed in water, their mass does not change. They seem to feel lighter, though, because of buoyancy. Archemedes's principle states that the force pushing on an object under water, is equal to the mass of the water it has pushed out of the way. So things apear lighter because the water is actually helping to push it … NettetFor the waves to keep moving back and forth, something needs to push them.
