Calculating Centrifugal & Coriolis Forces at Rest

In summary, centrifugal and Coriolis forces are inertial forces that arise due to the rotation of a frame of reference. Centrifugal force is an outward force that appears to act on objects in a rotating system, while Coriolis force is a deflective force that appears to act on objects in motion within a rotating system. The formula for calculating centrifugal force is Fc = mω^2r, and the formula for calculating Coriolis force is Fc = 2mωv. The main difference between these forces is that centrifugal force acts on objects within a rotating system, while Coriolis force acts on objects in motion within a rotating system. In most cases, these forces can be ignored, but

Homework Statement
Calculate the values of the centrifugal and the Coriolis forces in a mass of 20g placed at a distance of 10cm from the axis of a rotating frame of reference, if the angular speed of rotation is 10 radians per second.
Relevant Equations
n/a
so I can find the centrifugal force but shouldn't the Coriolis force be 0 because the mass is at rest?

At rest as viewed in which frame?

1. What is the difference between centrifugal and Coriolis forces?

Centrifugal force is the force that acts on an object as it moves in a circular path, pulling the object away from the center of rotation. Coriolis force is the force that acts on an object as it moves in a rotating reference frame, causing the object to veer to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.

2. How do you calculate the centrifugal force at rest?

The centrifugal force at rest can be calculated using the formula Fc = mv^2/r, where Fc is the centrifugal force, m is the mass of the object, v is the velocity, and r is the radius of the circular path.

3. What is the formula for calculating Coriolis force at rest?

The formula for calculating Coriolis force at rest is Fcor = 2mωv, where Fcor is the Coriolis force, m is the mass of the object, ω is the angular velocity, and v is the velocity of the object.

4. How do these forces affect objects at rest?

Centrifugal and Coriolis forces do not have an effect on objects at rest. They only come into play when an object is in motion.

5. What are some real-world applications of calculating centrifugal and Coriolis forces?

Some real-world applications of calculating centrifugal and Coriolis forces include predicting the trajectory of objects in space, understanding the behavior of weather systems, and designing efficient centrifugal pumps and turbines.
