If a cup of water is dropped, the water will tend to stay inside the cup momentarily due to inertia. However, once the cup hits the ground and stops moving, the water will then spill out of the cup due to the lack of support from the container.
Centrifugal force is responsible for keeping water in a spinning cup. As the cup rotates, the water inside is pushed towards the edges by this force, causing it to stick to the sides of the cup rather than spill out.
Because the effect of gravity doesn't really care about density -- all objects are accelerated at the same rate (ignoring wind resistance). Since the cup is feeling wind resistance, but the water isn't (since it's in the cup), the water is experiencing "positive" g-forces, even while falling. So gravity keeps the water in the cup.
It doesn't spill? Try it and see how tricky this is; it can be done, but you have to practice a bit. The cup of water has inertia, the tendency to remain stationary if stationary, and to remain in uniform motion if in uniform motion. Pulling the napkin out quickly and carefully enough does transfer a little energy to the cup, but if done correctly there is not enough energy to overcome the inertia.
When filling a cup/glass with full water the card/lid will not stay up.
It is not an insult to spill water in Spain.
If you mean *exactly* one cup by volume, you have the iceberg scenario. The cup of frozen water will be less dense, so it will weigh less. If you just freeze a cup of water, don't spill any, and *don't* trim the excess to bring the volume back to exactly one cup, then it will weigh exactly what it did at room temp.
No. Water expands when it freezes so when it melts, it will take up a smaller volume.
Yes, when a cup of water is held upright and then dropped, the water inside the cup will spill out as it falls. This is due to the inertia of the water inside the cup, which causes it to continue moving forward even as the cup falls. As a result, the water spills out of the cup and falls alongside it. This is also why it's important to be careful when carrying liquids, as sudden movements or changes in direction can cause them to spill or slosh around.

To flip a cup of water without dropping any water, you need to increase the speed of the flip so that the force keeps the water in the cup against the pull of gravity. This requires practicing the right technique and mastering the motion to create a controlled flip that does not spill any water. It also helps to use a cup with a wide opening to provide more stability during the flip.
one sachet every night. pour contents in a spill proof cup, add water , shake and drink immediately
In an oil spill in the ocean, the oil rises to the top because it is less dense than water, creating an oil slick on the surface of the ocean. A Styrofoam cup is less dense than a ceramic cup, so the Styrofoam cup will float in water and the ceramic cup will sink.
