How is centripetal force created?
You have a centripetal force whenever you have any force that attracts an object towards the center of its circular movement. In some cases, the centripetal force is what keeps an otherwise free object in a circular (or elliptical) trajectory in the first place - like when the Sun attracts the planets. In other cases - such as in a flywheel - the outer parts pull outwards (because of their inertia), so, by Newton's Third Law, the center of the movement pulls inward, providing the centripetal force. (If the outward pull is too strong, the objects that moved in a circular trajectory will break away.)
What are some examples of centrifugal force as present in nature?
Centrifugal forces at present do not exist in nature. However, the opposite of centrifugal forces, centripetal forces, do exist. Centrifugal forces are used only to explain that centripetal forces need an opposite force to act against it.
What is the difference of centripetal force and centrifugal force?
Centripetal force is directed toward the center of rotation of an orbiting body or object following a curved path. Centrifugal force is the apparent force, equal and opposite to the centripetal force, drawing a rotating body away from the center of rotation, caused by the inertia of the body. Whenever you see a moving object that's not traveling in a straight line, you know that a force is acting upon it. That's because objects tend to resist changes to their velocities. The greater the mass, the greater the resistance to changes in velocity. That's called inertia. Objects at rest tend to stay at rest, and objects in motion tend to stay in motion, unless acted upon by some external force. (See Newton's First Law.) Since velocity is a vector -- remember vectors have magnitude AND direction -- any change in an object's direction constitutes a changes in its velocity. When an object is flying around in a circle, its velocity is constantly changing because its direction is constantly changing! That means a force is working on it. That force is the centripetal force, and since force is equal to mass times acceleration, there must be an acceleration involved. You guessed it -- centripetal acceleration. In short: Centrifugal force is away from the center and centripetal force is towards the center. In even shorter: Centripetal force is real. Centrifugal force doesn't exist.
Why is centrifugal force called a pseudo force?
This is because it is not a force. It is a reflection of newtons 1st law, any object will continue along it path in a straight line unless another force acts on it. So when an object is constrained to rotate around a point, a circular path, it at all times will try to 'fly off' on along a tangent (a straight line from where it is now). This is what is called centrifugal forces. The only real force that acts is centripetal force, which is the force required to keep the object on circular path. This force acts directly towards the centre of the circle about which the object rotates. That is to say to keep the body in the place , where it is, and to balance the centripetal force, centrifugal force comes into play. it has no cause of existence without centripetal force,hence it is called pseudo force. Alternate answer: Centrifugal force is not a pseudo force. It is called a pseudo force because some neglect the vector derivative. Centrifugal force comes from the vector derivative of the vector energy Ev= mcV. The centrifugal force is f = - mcDel.V. The minus sign indicates motion away from the center, center fleeing , centrifugal.
When you are rounding a curve what force comes into play?
Centrifugal. "Pulling to the outside" is strictly "trying to go straight on" which is what would occur if you didn't apply forces to take you round the curve.
What is the reaction force to centripetal force in a centrifuge?
The centripetal force is the force with which the centrifuge pushes some object inwards. The opposite force, of course, is the object pushing the centrifuge outwards.
What are some examples of centripetal forces?
Centripetal force is a force that makes a body follow a curved path. An example of centripetal force is gravity making something in space orbit Earth. Mud flying in circles from a tire going down the road is centripetal force.
What kind of force that the tornado have like centripetal force centrifugal force?
Hi, Well the force is centripetal force during a body is initially attacked by the tornado,when the body started swinging in the tornado from the surface of the earth,the time when body covers some distance from downward to upward is the time when centrifugal force is applied.... That means tornado have both the centripetal force and centrifugal force..... Thanks you!
What sport involves the centripetal force?
A hammer thrower uses the centripetal force to control the hammer-head while its kinetic energy is built up for release
What is a gravitational pull also called?
gravitational force of attraction/gravity -- force -- weight -- centripetal force, under some circumstances
When you are in roller coaster you never fall down even when you are upside down Why?
It is true that the centripetal force is directed towards the center of the circle but in addition to the centripetal force there is another force called centrifugal force which is reaction force. The centrifugal force is directed opposite to the centripetal force, i.e.,outward. It is due to this force that we never fall down even when we are upside down. Technically, you are under the same downward acceleration at all times. When you are thrust up by the ride, it takes some time for the downward acceleration to stop the upward movement. That "some time" is your free upside-down ride.

What statement is self -contradictory?
Statements that are self contradictory are paradoxes or oxymorons. Some are trivial some are funny. A funny one would be military intelligence or military music. A more serious one is the old one about an immovable object and an irresistible force
What are some properties that the moon and earth share?
both are planets and are orbit with centripetal force. think about the atmospheres. They orbit around one another.
