Can you create 0 gravity chamber and how?
yes, by creating an opposing acceleration equal to the gravitational field strength (9.81m/s2) this would balance out the force of gravity and u could float. It can be done with magnetism, or with centripetal forces
How is centripetal force calculated?
Centripetal force is not a force like gravity, which is there for any object with mass in a gravitational field (such as that of the earth, the sun), but a force which must be present in order to move in a circle. There is never a situation where you say "aha, this generates a centripetal force", but if something is moving in a circle (and certain types of ellipse) you can say that one of the forces already present (such as gravity, or tension for a weight on a string) is providing the required centripetal acceleration for circular motion. In practice though, the cheap and dirty trick is just to say the centripetal force is equal to (mass of the moving object x velocity^2) / (the radius of the circle).
How does centripetal acceleration depend upon the object's speed and the radius of the circle?
The centripetal acceleration is equal to velocity squared over radius. a=v^2/r
Why can you consider the weight of the hooked masses as equal to the centripetal force?
The force of gravity on the hooked masses supplies the tension in the string which in turn supplies the centripetal force that keeps the body rotating.It would be better to say that the weight of the hanging masses IS the centripetal force that keeps the body revolving.... and so the two forces are equal because there is really on one force.
Does an object have more potential energy the more mass it has?
Yes - gravitational potential energy is equal to mass x gravity x height.Yes - gravitational potential energy is equal to mass x gravity x height.Yes - gravitational potential energy is equal to mass x gravity x height.Yes - gravitational potential energy is equal to mass x gravity x height.
How centripetal force equals to gravitational force?
The centripetal force is equal to the gravitational force when a particular body is in a circle. For a body that is in an orbit, the gravitational force is equivalent to the centripetal force.

How do they affect the centripetal force?
If an object moves in a circle, the centripetal acceleration can be calculated as speed squared divided by the radius. The centripetal force, of course, is calculated with Newton's Second Law: force = mass x acceleration. Therefore, the centripetal force will be equal to mass x speed2 / radius.
How does centripetal acceleration depend upon the object's speed and the radius of the circle?
The centripetal acceleration is equal to velocity squared over radius. a=v^2/r
What is the relation between centripetal and centrifugal force according to newton third law?
They are equal and opposite.

Why do people not fly off the surface of the rotating earth into space?
Because the gravitational force between the earth and each person is sufficient centripetal force to maintain circular motion with a radius equal to the Earth's equatorial radius and angular velocity of (pi/12) radians per hour.
What prevent the planets from flying off into space?
The easy answer is gravity. The pull of a star's gravity keeps the planets in orbit in almost equal amounts of centripetal force pulls them away.============================================Another contributor clarified:The answer is 'gravity'. The more massive the body, the more gravity it has."Centripetal force" is any force that pulls awayof the path, such as swinging around a weight attached to a string. The faster you spin it, the heavier it seems to become.
What holds the earths orbit around the earth?
WHAT HOLDS THE EARTH IN ITS ORBIT REVOLVING AROUND THE SUN?In fact the Earth's orbit is a sort of equilibrium. The Earth's revolutions around the Sun provides it with centripetal force. A force that wants to eject it out of its orbit. That same force that wants to eject you out of your car when you are in a tight bend.However (and fortunately) there exist a strong gravitational force (attracting force) between the Sun and the Earth. It happens that the centripetal force ejecting the Earth is equal and hence balances the gravitational force pulling it towards the earth. As a result the Earth continues its motion around the Sun, undisturbed.As a conclusion, I'll say that what holds the Earth around the Sun it a result of 2 forces acting opposite to each other, namely the centripetal force pulling it away from the Sun and the gravitational force pulling it towards the Sun.
Does an object have more potential energy the more mass it has?
Yes - gravitational potential energy is equal to mass x gravity x height.Yes - gravitational potential energy is equal to mass x gravity x height.Yes - gravitational potential energy is equal to mass x gravity x height.Yes - gravitational potential energy is equal to mass x gravity x height.
Why is gravitational potential energy equal to kinetic ebergy?
Gravitational potential energy is not equal to kinetic energy:MGY doesn't always equal (1/2)mv2. This holds true in the CHANGE of gravitational potential energy being equal to the CHANGE in kinetic energy because of the Law of Conservation of Energy, Mass, and Charge.
