This is an example of centripetal (circular) motion. The water stays in the bucket
because of inertia
. The water wants to fly off from the circle, but the bucket gets in the way and keeps it in place. This is the same effect you feel when you go around a tight corner in the car and get squished against the door.
Why does water remain in a pail that is whirled in a vertical circular path Why doesn't the water spill out when it is upside down?
It stays in the pail because
due to circular motion it develops a centripetal acceleration which pulls the water towards the center
and hence the water doesn't spill. This centrepetal accelearation provides a centripetal force too.
Why does water remain in a pail that is whirled in a vertical circular path?
A pail of water can be whirled in a vertical circular path and such that no water is spilled. …
If the centripetal acceleration is greater than the acceleration due to gravity
, then the water will remain in the pail.
Why the water does not fall out of a bucket when it is whirled?
Why the water does not fall out of a bucket when it is whirled in a vertical circle? In this case, the net force just equals the weight force, and since the bucket is moving in a circle, this
net force must be the centripetal force
. so the water will not fall out if the bucket is whirled around once every 2 s.
How can the water stay in place even at the point where it is over your head?
Gravity
– the force pulling down on everything – is still at work even when the bucket and water are above your head. The water's inertia wants to keep the water traveling in a straight path, but gravity is acting on the water, causing it to fall in a downward path that will eventually hit the earth.
Is it possible to whirl a bucket of water fast enough in a vertical circle?
Yes
, it is possible to whirl the bucket in the vertical circle without the fall of water.
When a pail of water is flowing in a vertical circle the water does not fall out at the top of the loop when the speed is?
Correct Option: B. When a pail of water is swung in a vertical circle, the water does not fall out at the top of the loop when
the speed is great enough
. At every point in the circle the water tries to fall vertically out due to the force of gravity g but also tries to move in a straight line due to its circular motion …
What would happen to the water if you stopped the motion of the bucket while it was turned upside down?
When you simply turn a bucket upside-down, we know that
the water falls out of the bucket because gravity is pulling it towards the earth
, but the bucket doesn't fall because you are holding it above the earth – exerting a force opposite to gravity.
What laws of motion can you apply in the spinning cup of water?
In simplest terms, the water cup is undergoing
uniform circular motion
. Uniform circular motion can be described as the motion of an object in a circle at a constant speed. As an object moves in a circle, it is constantly changing its direction. At all instances, the object is moving tangent to the circle.
Is it possible for a car to move in a circular path?
No
, because moving in a circular track implies a changing in the direction of motion, which leads to the existence of the centripetal acceleration.
When a bucket filled with water is revolved fast in a vertical circle the water does not fall even when the bucket is inverted?
Explain why water does not fall? The water
is strongly pulled by
the force of gravity of the earth's surface when a bucket of water is just raised and inverted, whereas there is no normal force below as there is no surface to limit the water's fall it falls.
Is centrifugal force?
Centrifugal force is
the apparent outward force on a mass when it is rotated
. Think of a ball on the end of a string that is being twirled around, or the outward motion you feel when turning a curve in a car. In an inertial frame, there is no outward acceleration since the system is not rotating.
When a person spins a bucket of water?
gravity. When a person spins a bucket of water in a circle, the force acting on the bucket to keep the water inside is called
Centripetal Force
. When a person spins a bucket of water in a circle, the force acting on the bucket to keep the water inside is called Centripetal Force.
Why does the water spill out when you tilt the jar to the side?
Atmospheric pressure
(the pressure exerted by the surrounding air) is the force that holds the index card in place. … If you tip the jar at all, air will come into the jar and break the seal, causing the water to pour out. Tip the jar sideways and the water falls out of the jar.
What happen when you pour slowly the sand into the glass of water?
If you pour water on the sand,
the water seems to disappear into the sand
. … This happens because under pressure the sand grains actually push each other slightly farther apart, which makes more space between them. This means there is more space for water to flow into, resulting in a dry footprint on the beach.
What force pulled the water out of the whole?
Gravity
is pulling the water (and cup) back to Earth, so the water takes the path of least resistance back to Earth – out of the holes.
