Centrifugal force is an apparent force that acts outward on a body moving around a center, arising from the body's inertia.
How does centrifugal force differ from centripetal force?
Centripetal force is a real force that acts toward the center, causing circular motion. Centrifugal force is an apparent force perceived when in a rotating frame.
In what type of motion is centrifugal force observed?
Centrifugal force is observed in circular or rotational motion.
Why is centrifugal force considered a 'fictitious' or 'apparent' force?
Because it is not due to any physical interaction but rather the inertia of a body in a rotating frame.
Give an example of centrifugal force in real life.
An example is water being pushed to the sides of a washing machine drum during its spin cycle.
What role does inertia play in centrifugal force?
Inertia causes a moving object to continue in its motion, which creates the outward force as the object moves in a circular path.
What is required to keep an object moving in a circular path?
A centripetal force is required, pulling the object towards the center of the circular path.
What happens to centrifugal force when the speed of rotation increases?
The centrifugal force increases because it is dependent on the speed of rotation.
How does mass affect centrifugal force?
Centrifugal force increases with the mass of the object being rotated.
How can centrifugal force be increased without changing speed or mass?
By increasing the radius of the circular path.
Explain the relationship between radius and centrifugal force.
Centrifugal force increases with the increase in radius of the circular path, assuming constant speed and mass.
In which direction does centrifugal force act?
Centrifugal force acts outward, away from the center of rotation.
Does centrifugal force do work on the object in motion?
No, because force in the radial direction does not result in displacement parallel to the force.
How is centrifugal force perceived differently by observers inside and outside the rotating system?
Observers inside perceive it as a real force pushing them outward, while external observers see it as inertia opposing centripetal force.
What equation is used to calculate centrifugal force?
Centrifugal force can be calculated with F = m*v^2/r, where m is mass, v is velocity, and r is radius.
