Yes, centripetal force helps keep water in a cup when the cup is spun in a circular motion. As the cup moves, the centripetal force acts toward the center of the circular path, keeping the water pressed against the bottom and sides of the cup. This force counteracts the tendency of the water to spill out due to inertia, allowing it to remain inside the cup during the motion.
A drain plunger is sometimes (though rarely) called a force cup. Asking for a force cup at the hardware store will only slow your ability to get one, and it could easily result in your being thought of as a "wise guy" or something else.
That rule was there by f.I.F.A till the year1970. The new world cup is a circulating cup.
The original world cup, or the Jules Rimmet trophy was a rotating cup with a rule then that a country that wins the world cup for the third time ever can keep it for good. Brazil won their third world cup in 1970.And so kept it.It was later stolen.
The cup of water is as hot as the bath tub full of water as they are at the same temperature.
The world cup from the year 1970 onwards is a rotating trophy.
When a cup of water is twirled at 360 degrees, the centripetal force created by the motion of the cup keeps the water inside. This force acts inward, preventing the water from spilling out even when inverted. As long as the centripetal force is greater than the force of gravity pulling the water downward, it will remain in the cup.
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.
You are right, you can flip a cup very fast and no water will fall out. Depending on how you flip it, that is. Due to centripetal force, the water "wants" to spread away from the axis of rotation. If the axis is the top of the cup, the water is off center and will just be pushed toward the bottom, from which it cannot escape. If the axis is the water, it will probably fall out a little bit, but not all of it. The cup is most likely spinning too fast for it to fall out. Once the water starts to fall, it is caught again. :D
thermos cup
Yes it will .
No, It doesn't. If you want to keep hot water hot for a longer time use a polystirene cup.
A paper cup typically does not keep water hotter than a plastic cup. Paper is a poor insulator compared to plastic, so heat is more likely to escape from a paper cup, leading to faster cooling of the water inside.
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.
Yes, they both fall at the same rate because the force of gravity is the same for both the cup and the water. True
The two forces acting on the paper cup and its contents to keep it upright are gravity pulling the cup downward and the normal force exerted by the table in the opposite direction, preventing the cup from falling.
Well, it is complicated, the trapped gas uses the force of pressure against the underlying water with the same amount of force that the water is putting on the gas. So the water doesn't go in the cup because the air is pushing it back.
Yes, they both fall at the same rate because the force of gravity is the same for both the cup and the water. True
