The two experience a rotating object. Centripetal force is a force that acts on an object moving in a circular path, directed toward the center of the circle. During rotation, the centrifuge is a force that moves the rotor and rotates an object. The centripetal force keeps objects moving around circles, pointing at the center of the circle.
Centrifugal force is an apparent force that acts on an object moving in a circular path, directed away from the center of the circle. This force is a result of inertia, or the tendency of an object in motion to stay in motion. It is not a real force and can be thought of as a “pseudo force” or an “illusion” caused by the circular motion of the object.
In contrast, centrifuges are apparent outside forces on objects that move around in circles. The sensation when driving the car gets you to jump in and out of the car.
Explanation of centripetal force and centrifugal force
Centripetal force is the force that acts on an object to keep it moving in a curved path. It is always directed towards the center of the circular path and is equal to the mass of the object multiplied by its velocity squared divided by the radius of the circle.
Centrifugal force is the apparent force that appears to push an object away from the center of a circular path. It is an apparent force because it is not a real force, it is the result of an object’s inertia as it is pulled around a curved path.
Centrifugal force is directed away from the center of the circular path and is equal to the mass of the object multiplied by its velocity squared divided by the radius of the circle.
Developing formulas for centripetal force and centrifugal force
- Centripetal Force: (F)cp = mv2/r
- Centrifugal Force: (F)cf = mv2/r
How does Centripetal Force work?
Centripetal force is the force that is responsible for keeping an object in a circular path. This force acts upon an object that is moving along a curved path, pulling the object toward the center of the circle. The magnitude of the centripetal force is proportional to the mass of the object and the square of its velocity and is directed toward the center of the circle.
It is equal to the product of the object’s mass and the square of its velocity, divided by the radius of the circle. In practical terms, this means that the greater the velocity of the object, the greater the centripetal force required to keep it in a circular path.
How does Centrifugal Force work?
Centrifugal force is an inertial force that acts on objects in a circular motion and is directed away from the center of rotation. This force is caused by the centripetal force, which is the force that is directed toward the center of rotation.
As an object in motion follows a curved path, the centripetal force is directed toward the center of rotation, while the centrifugal force is directed away from it. The magnitude of the centrifugal force is directly proportional to the mass of the object and the square of the object’s velocity.
Centrifugal force is a feeling
Centrifugal force is not a feeling, but rather a physical force. It is an inertial force, directed away from the center of rotation, that appears to act on all objects when viewed in a rotating reference frame.
Centripetal force and acceleration
Centripetal force is the force that is directed toward the center of the circle in which an object is moving. It is the result of an object’s inertia causing it to resist changes in velocity. It is the force required to keep an object moving in a circular path.
Centripetal acceleration is the acceleration of an object as it moves in a circular path, due to the centripetal force acting on it. It is the rate at which the speed of the thing changes as it moves along the circular path.
Sources of Centripetal Forces
- Friction: Friction is a centripetal force that is caused when two objects move relative to each other. This force acts in a direction that is opposite to the direction of motion and is the result of the two objects pushing against each other.
- Gravity: Gravity is a centripetal force that acts between two objects that have mass. The force of gravity pulls them together and is responsible for the orbiting of planets around the Sun.
- Tension: Tension is a centripetal force that is caused when an object is attached to another object by a rope or other material. The force of tension pulls the two objects together and is responsible for the movement of a yo-yo.
- Magnetic Force: Magnetic force is a centripetal force that is caused when two objects with magnetic properties interact. The force of magnetism pulls the two objects together and is responsible for the movement of magnets in a magnetic field.
- Electric Force: Electric force is a centripetal force that results from the attraction or repulsion between two objects with electric charges.
- Inertia: Inertia is a type of centripetal force that occurs when an object is moving in a circle due to its own momentum, such as when a spinning top is spinning around on a table.
Sources of Centrifugal Forces
Centrifugal force is an inertial force that is generated when an object is rotating. Common sources of centrifugal force include amusement park rides, washing machines, and centrifuges. Other sources of centrifugal force include cars accelerating and turning, skaters spinning, and cyclists leaning into a turn.
Centrifugal force and Newton’s laws of motion
Centrifugal force is a fictitious force that is used to explain the effects of inertia in rotating systems. It is not a real force, but rather an apparent force that is the consequence of the inertia of an object moving in a curved path.
Centrifugal force is related to Newton’s laws of motion, as it is the result of an object’s inertia in response to the centripetal force that acts on it. Newton’s first law states that an object in motion will remain in motion in a straight line unless acted upon by an external force.
This means that an object in a circular path must be acted on by a force directed toward the center of the circle, known as the centripetal force. This force is required to keep the object moving in a curved path and is opposed by the centrifugal force that is the result of inertia.
Newton’s second law states that the acceleration of an object is proportional to the force applied to it, and this applies to the centrifugal force as well.
Examples of centripetal force
- A car rounding a bend: When a car goes around a bend, the friction between the tires and the road provides a centripetal force that keeps the car on the curved path.
- A person swinging a ball on a string: The tension in the string provides a centripetal force that keeps the ball moving in a circle.
- The Earth orbiting the Sun: The gravitational force between the Earth and the Sun provides a centripetal force that keeps the Earth in its orbit.
Examples of centrifugal forces
- The force that keeps a person from flying off a spinning amusement park ride is an example of a centrifugal force.
- The force that keeps a car from skidding when it takes a sharp turn is an example of a centrifugal force.
- The force that keeps a satellite in orbit around the Earth is an example of a centrifugal force.
- The force that keeps a planet in orbit around the Sun is an example of a centrifugal force.
FAQs
A centripetal force is a force that acts on an object and is directed toward the center of the circular path of the object. This force is responsible for keeping the object in a circular motion.
A centrifugal force is an apparent force that acts on an object in a circular motion and is directed away from the center of the circular path. This force is the result of inertia and is the opposite of the centripetal force.
Some examples of centripetal forces include gravity, friction, tension, and electromagnetic forces.

5. The force felt when a person is spinning in a tire swing
6. The force felt when a person is twirling a baton
7. The force felt when a person is riding a merry-go-round
8. The force felt when a person is ice skating and spins around
Centripetal and centrifugal forces work together to keep an object in a circular motion. The centripetal force acts towards the center of the circular path, while the centrifugal force acts away from the center. The two forces balance each other out, allowing the object to stay in a circular motion.
A centripetal force affects an object’s motion by causing it to move in a curved path, rather than a straight line. The centripetal force acts towards the center of the curved path and is what keeps the object moving in its curved trajectory.
A centrifugal force affects an object’s motion by creating an outward force that is equal to and opposite to the centripetal force. This force acts away from the center of the curved path.
