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!

Why is the centrifugal force the ladybug feels in the rotating frame called fictitious force?
This is a term from classical mechanics. A fictitious force is a force that is only present in a so-called non-inertial frame. This means that the observer is experiencing some kind of acceleration. The point is that if the observer is accelerating then he might see some forces that are not really forces at all. If you are in a rotating frame you are accelerating, and you feel a centrifugal force. However anyone looking at you while not rotating themselves will say that there is no such force at all. Imagine you are on a horse in a merry-go-around and the thing malfunctions and starts to rotate very rapidly. You will feel the centrifugal force trying to blow you away from the center. However someone standing next to the merry-go-around sees no such force. What he sees is you holding on to the horse, but it is YOU holding onto the horse that is providing a force, if you would let go you would just fly in a straight line and no force would work on you. It is a little difficult to explain it very well in words, in the relevant links I have posted a link that points to the wikipedia article for the Coriolis force (a fictitious force) and figure 1 there shows a nice picture of the above. In General Relativity however, there is no preference for inertial frames anymore and you are valid in claiming there is a force pushing outwards. This force is then gravity. This is direct consequence of the equivalence principle that states that gravity and acceleration are indistinguishable (in a suitable limit).

A pushing force 8P
Without a force to stop or slow a coasting object the object will coast forever in what kind of line?
In a straight line. unless diverted by a on coming force

What kind of force moves an object away (4th grade)?
An object can be moved away by a force like pushing or pulling. This force changes the object's position or direction of motion. Examples include pushing a toy car across the floor or pulling a wagon up a hill.
What are two kind of xylem and their functions?
1. Centripetal xylem 2. Centrifugal xylem both types are involved in conduction
What kind of a force is centripetal force?
When a body is forced to follow a curved path and be directional to the velocity of the path it is known as a centripetal force. Simply put, centripetal force is the cause of circular motion. An example is a loop within a roller coaster that goes upside down, the centripetal force is applied to the track making the coaster travel through at speed.
When you are rounding a curve what force comes into play?
When rounding a curve, the centripetal force comes into play. This force is directed towards the center of the curve and is necessary to keep an object moving in a curved path rather than continuing in a straight line.
Which kind of force do you use to kick a ball?
Gravity, friction, air resistance, centrifugal force, may be more.
What kind of force does a tornado have which keeps it to have that funnel shaped wind?
The wind in a tornado moves in a circular fashion as it is pulled inward by the pressure gradient force resulting from the low pressure at the center of the tornado.
Centripetal forces cause object to move in what kind of path?
Centripetal force is a force that makes a body follow a curved path: it is always directed orthogonal to the velocity of the body, toward the instantaneous center of curvature of the path. The term centripetal force comes from the Latin words centrum ("center") and petere ("tend towards", "aim at"), signifying that the force is directed inward toward the center of curvature of the path. Isaac Newton's description was: "A centripetal force is that by which bodies are drawn or impelled, or in any way tend, towards a point as to a center."
How does radius speed mass affect centripetal force?
They are the same factors affecting any other kind of force. If the centripetal force is gravitational, then it depends on the masses of the two bodies involved and the distance between them. If it's electrostatic, then it depends on their charges and the distance between them. If it's the force that bends a car around a curve, then it depends on the bank in the pavement and the coefficient of friction between the road and the tires.
What does A vortex have to do with an tornado?
A vortex is a spinning flow of air or liquid. In a tornado, a vortex forms when warm, moist air meets cool, dry air, creating a rotating column of air that extends from the base of the storm cloud to the ground. This rotating vortex is what gives a tornado its destructive power.
What kind of force is changing directions?
A force that changes direction is considered a vector force. This means that not only does it have a magnitude, but it also has a specific direction in which it acts. Examples of such forces include tension in a rope, gravitational force, and magnetic force.
Whats the force that keeps electrons in orbit?
To put it in its simplest form: Attraction to the (positively charged) nucleus, repulsion by other negative electrons and (kind of) centripetal force. The real story is far to complicated to put it down here: quantum mechanical model (theory).
What kind of force causes something to change direction?
A centripetal force causes an object to change direction by pulling it towards the center of its circular path, thereby keeping it in a curved motion rather than moving in a straight line. This force is necessary to counteract the object's tendency to move in a straight line due to inertia.
