OldEngr63 said:Looks like you wrote down
CF = m v2/r
but then you calculated the circumference, C = 2 π r
and then you said,
CF = r C2/6 = C2
Why would you expect the centripetal force to be equal to the square of the circumference?
It really is not.
Try it again, starting with CF = m r ω2 and see how that turns out for you. You failed to get the time information into the problem.

To calculate centripetal force for a 6 kg object, you will need to know the mass of the object, the velocity at which it is moving, and the radius of the circular path it is following. The formula for calculating centripetal force is F = (m*v^2) / r, where F is the centripetal force, m is the mass, v is the velocity, and r is the radius.
Centripetal force is typically measured in units of newtons (N), which is the standard unit for force in the International System of Units (SI). However, other units such as pounds (lbs) or dynes (dyne) may also be used to measure centripetal force.
No, centripetal force cannot be negative. Since it is a force that is directed towards the center of a circular path, it is always positive. If the direction of the force changes, it is simply referred to as a different type of force, such as centrifugal force.
The mass of an object has a direct relationship with the centripetal force. As the mass of the object increases, the centripetal force required to keep it in a circular path also increases. This means that a heavier object will require a stronger force to maintain its circular motion compared to a lighter object.
If the velocity of an object increases, the centripetal force required to keep it in a circular path will also increase. This is because the force needed to overcome the object's inertia and maintain its motion in a curve is directly proportional to its speed. Therefore, a faster-moving object will require a greater centripetal force to keep it in a circular path.
