How much force is needed to keep a 20N stone from falling?
20 N (upward)
What force is needed to keep an object in circular motion?
Centripetal force
What provides the centripetal force needed to keep the stopper moving in a circle?
The string
What is the force of gravity acting on the block (the weight) in water?
The force of gravity on a block is the same, whether it is in air or in the water. The apparent weight (the force you need to keep it from falling) is less in water, due to the buoyancy force, which counteracts the weight.
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 will happen if you keep stone on stone?
centrifugal force
What force is needed to keep an object in circular motion?
Centripetal force
Is force always neede to keep an object moving?
Force is never needed to keep an object moving unless there is an opposite force trying to slow the object.
Where does force needed to keep planets orbiting the sun come from?
The force is provided by the Sun's gravitational attraction.
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.
Which fitness skill is the ability to maintain equilibrium against the force of gravity or to keep from the falling when still or when moving?
balance

The string
How much force is needed to move an object?
No force is needed to keep an object moving. An object with no forces on it keeps moving at a constant speed in a straight line. If there is any force acting on it to make it slow down, then you need just enough force to cancel the first one, in order to keep it moving.
How much force is needed to keep a 2kg object moving?
No force is needed to keep an object moving. An object with no forces on it keeps moving at a constant speed in a straight line. If there is any force acting on it to make it slow down, then you need just enough force to cancel the first one, in order to keep it moving.
Where is a paradox in Harry Potter and the Philosopher's Stone?
Catch-22 paradox: "You can only have the thing you need if you are not in need of it" Harry did not need the Sorcerer's Stone, but Voldemort did. Harry got the stone because he needed to keep it away from Voldemort, not because he needed it for himself specifically.
