The formula for centrifugal force is f - mcDel.V -mcv/r cos(VR).
Another formula is Fcf + mv2/r + mrw2
Here, m mass of the body in circular motion (kg)
v its linear velocity (m/s)
r radius of the curve (m)
w angular velocity (rad/s)
The force of friction is a force acting from a surface in the opposing direction of the body's tendency to slide. It is due to both the normal force pushing from a surface against a body and a condition of the surface called the coefficient of friction. Dependent on whether the body is at rest or moving there is a different coefficient of friction. Static friction is used when the body is at rest and is defined by
Ffriction=Nμs
where Ffriction is the force of Friction, N is the normal force, and μs is the coefficient of static friction. Kinetic friction is used when the body is sliding along the surface and is defined by
Ffriction=Nμk
where μk is the coefficient of kinetic friction.
Consider a body moving at constant speed in a circular path of radius r. In dt seconds, it covers a distance of ds through an angle of dA. Its change in velocity is dv. We then have the following equations:
1. ds = rdA (from length of arc = radius x angle subtended at centre of circle in radian)
2. ds = vdt (from distance = speed x time)
3. dv = vdA (Here, a vector diagram will help)
Note that these are only approximations. Due to lack of the approximation sign, I have used the equal sign itself.
From 1 and 2,
rdA = vdt
dA = vdt/r --------- 4
Substituting dA = vdt/r into 3, we have:
dv = v(vdt/r)
dv/dt = v2/r
As the small changes approach zero,
lim(dv/dt) = v2/r
=> Centripetal acceleration = v2/r (since a = dv/dt)
Note here that they are exactly equal.
From Newton's second law,
Centripetal force = mv2/r = mw2r
where w is the angular velocity and v = wr.
First, calculate the centripetal acceleration, with one of these formulae:
a = v2/r
a = omega2r
Where "v" is the speed, "r" is the radius, and "omega" is the angular speed, in radians/second.
Then, you can use Newton's Second Law:
F=ma
to find out the force required to keep a certain mass moving in a circle.
Centripetal acceleration =v^2/r and the centripetal force is mv^2/r.
f =mv2/r

a=(v^2)/r or a=r(angular velocity)^2
Centripetal force has the following formula: Fcentripetal = m times V2/r What that says is that for a constant r in an example, the Fcentripetal is proportional to V2. The centripetal force is proportional to the square of the velocity of the object.
No; "centripetal" implies an inward force.
no, but rotation can produce centripetal force

Centripetal force is always directed towards the center of the circle of motion that an object is traveling in.
a=(v^2)/r or a=r(angular velocity)^2
One formula for centripetal force is v2/2 - the square of the velocity (speed, actually) divided by the radius. Another is omega2r, where omega is the angular speed, in radians/second.One formula for centripetal force is v2/2 - the square of the velocity (speed, actually) divided by the radius.

When speed is doubled, the centrifugal (or centripetal) force increases by a factor of 4. One formula you can use (for centripetal acceleration) is: a = v2 / r. Force, of course, is proportional to acceleration.
No; "centripetal" implies an inward 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.
no, but rotation can produce centripetal force
Answer It is the force which keeps a body moving in circular motion. Centripetal force is the force that acts opposite to cetrifugal force. Centripetal force is a real force. Centrifugal force is a pseudo-force
Centripetal force is found using the equation F=mv2/r m=mass v=velocity r=radius
The gravitational force IS the centripetal force in this case.
