What happens if you freeze stone?
it gets cold
What did Newton formulated about unbalanced forces?
Newton's third law of motion states that for every action there is an equal and opposite reaction. Now when we rotate a stone tied to a string we see that we are applying force to make the stone rotate but again this force should cause the stone to move towards the center as there is no other force to balance it. But it doesn't. Thats where a mysterious force called a pseudo force comes in. Pseudo force as it doesn't exist in reality and we assume its just there because the third law predicts it so. Its called the centrifugal force.
Weight is measured in?
Units of force, such as pound, newton, stone, etc.
What are the units of gravitational pull?
Acceleration of gravity is equal to negative 9.8 metres per second squared.The so-called "pull" of gravity is a force. The only difference between the 'pull'of gravity and the 'pull' of a rope is the direction. They're both forces.Here are some widely used units of force:-- newton-- pound-- ton-- stone-- ounce
What happens when you put jade stone with vinegar and acid pill?
Jade is not soluble in vinegar.
Two men applaying forces in different direction on a stone of 30kg and 5 healthy men applaying full force on the same and determining resultant reaction?
The stone will move in the direction of most force. In this case, the stone would move in the direction the five healthy men are pushing.
10 examples of law of acceleration?
-- A car accelerates in the direction of the net force on it, at a rate equal to the magnitude of the net force divided by the mass of the car. -- A stone accelerates in the direction of the net force on it, at a rate equal to the magnitude of the net force divided by the mass of the stone. -- A Frisbee accelerates in the direction of the net force on it, at a rate equal to the magnitude of the net force divided by the mass of the Frisbee. -- A baseball accelerates in the direction of the net force on it, at a rate equal to the magnitude of the net force divided by the mass of the baseball. -- A dog accelerates in the direction of the net force on it, at a rate equal to the magnitude of the net force divided by the mass of the dog. -- A book accelerates in the direction of the net force on it, at a rate equal to the magnitude of the net force divided by the mass of the book. -- A canoe accelerates in the direction of the net force on it, at a rate equal to the magnitude of the net force divided by the mass of the canoe. -- An airplane accelerates in the direction of the net force on it, at a rate equal to the magnitude of the net force divided by the mass of the airplane. -- A planet accelerates in the direction of the net force on it, at a rate equal to the magnitude of the net force divided by the mass of the planet. -- A cow accelerates in the direction of the net force on it, at a rate equal to the magnitude of the net force divided by the mass of the cow.
Why do you weigh more on Mt Everest?
Mt. Everest is made of stone which is really dense so the earth has more mass in that area. The more massive an object is, the more gravitational force it exerts. Your weight is the force with which the earth pulls on you.
Two men of 30kg applying force on a stone and 5 men applying force in same direction?
It is extremely unlikely that you will find 2 men of 30 kg!
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?
As force acting in a circular path is always tangential to the path
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
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.
Why a stone sinks in water?
Water exerts a force on anything that comes into contact with it, this is known as Hydric force. The force always pulls at the object, drawing it down. You will notice that if you put your hand under water, and bring it out slowly, the water seems to cling to your hand as it breaks the surface. This is why. Stones can't pull themselves out of water, so the Hydric force overpowers them and pulls them down.
When water freezes into a crack in a stone which direction does the water force itself?
The resulting ice expands in all directions. It is the part of this expansion that is pushing on the sides of crack that can make the crack wider, even breaking off pieces of stone.
What will happen if you keep stone on stone?
centrifugal force
Describe three situations in which a force changes the velocity of an object?
1). Force applied to a moving object, in the direction of its motion. Speed increases, direction remains unchanged. 2). Force applied to a moving object, opposite to the direction of its motion. Speed decreases, direction remains unchanged. 3). Force applied to a moving object, in an arbitrary direction not parallel to the direction of motion. Speed and direction both change. 4). (bonus): Force applied to a moving object, force is kept exactly perpendicular to the direction of motion at every instant. Speed remains constant, path of the motion becomes circular.
Is Stone Mountain a constructive force or a destructive force?
