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