Why A stone tied at the end of a string is whirled in a circle If the string breaks the stone flies away in tangential direction?
When the stone is whirled in a circle, it experiences centripetal force, which keeps it moving in a circular path. If the string breaks, the centripetal force is lost, causing the stone to move in a straight line tangent to the circle at the point where the string broke. This concept is described by Newton's first law of motion, which states that an object in motion will continue in motion in a straight line unless acted upon by an external force.
What forces would be at work if you were trying to move a huge block of stone?
If you were trying to move a huge block of stone, the forces of friction would be applied against you. To get the stone in motion, you must overcome static friction, the friction force that acts on objects that are not moving and is always working in the direction opposite of your applied force. Then, to keep it in motion, you must overcome sliding friction, which, though it takes effort to keep moving a stone, is substantially less than the effort to get a stone into motion originally.
What is the manifestation of centripetal force in a stone tied to a string and whirled horizontally?
The centripetal force in this scenario is manifested as tension in the string. The tension in the string acts as the centripetal force required to keep the stone moving in a circular path. If the tension in the string is too weak, the stone will not be able to maintain its circular motion and will fly off tangentially.
Why does a person lift a heavy stone immersed in water as compared to air?
If the question is asking "for what reason would a person lift a heavy stone immersed in water as opposed to air?" then the answer is buoyancy. When immersed in water there will be an upward force on the bottom of the stone due to the volume of water it has displaced. This upward force will make the stone seem lighter to the person lifting it by decreasing the amount of force they need to exert to lift it.
How much force is needed to keep a 20N stone from falling?
The force needed to keep a 20N stone from falling would need to be 20N or greater in the opposite direction to counteract the force of gravity pulling the stone downwards. This force would need to be applied vertically upwards to effectively balance the gravitational force acting on the stone.

What force does a 15 stone person exert on the Earth due to gravity where force is measured in Newtons?
On earth, 1 stone is the weight of 6.35 kilograms of mass.15 stone is the weight of 95.25 kilograms of mass = 933.49 newtons. (rounded)That's the magnitude of both forces ... the force that attracts the earth to the person,and the force that attracts the person to the earth. The net force on the soles of theperson's shoes is zero.

Why does mud attached with the wheel of a vehicle sprinkled away more if its speed increases?
An object moving in a straight line needs to have a force applied to it for it to change direction. A faster object requires a stronger force to change its direction by the same amount in the same amount of space as you did with the lower speed object. Imagine swinging a stone on the end of a piece of string around your head. The stone is moving in a circular motion and therefore it is always changing direction. The string is pulling the stone in a circular motion and is therefore acting as a force. Now the string can only take so much force so if you speed up the stone, the string has to apply more force to the stone in order for it to be changing direction all the time. Once the stone is going fast enough, the string will not be able to provide enough force and will break and the stone will fly off at a tangent. Think of the "stickiness" of the bits of mud as the string. As you speed up the wheel, the string (stickiness) breaks because it cannot provide enough force to keep the mud moving in a circle. If you're interested in this kind of stuff you should study mathematics which covers circular motion in the mechanics section
Where is the stone circle on the game runescape?
The stone circle is in varrock where dark wizards are.
Would you need the same force to keep the stone moving as you did to get it started?
This depends upon where the stone is.In a vacuum with no gravitational fields nearby you would need no additional energy to keep a stone flying, the first throw would do it and it would continue until another force acted upon it.To keep a stone moving on the Moon you will need to keep putting in sufficient energy to overcome the gravity there.To keep a stone moving on Earth you would have to keep putting sufficient energy in to overcome a higher gravitational field and the drag caused by the atmosphere.

What is the action and reaction in case of a stone suspended by a string?
Downward force on the stone ===> force of gravity. Upward force on the stone ===> tension in the string. Downward force is equal to the upward force. Total (net) force on the stone is zero. Acceleration of the stone is zero. It just hangs there.

What happens when you kick a stone your foot exerts a force on the stone and the stone exerts a force in size and in direction on your foot?
When you kick a stone, your foot exerts a force on the stone, causing it to move away. Simultaneously, the stone exerts an equal force back on your foot in the opposite direction, which can cause your foot to experience a reaction force or potential pain, depending on the force exerted by the stone.
