What happens when centripetal force is equal to the centrifugal force?
In any case, the centrifugal force is exactly the same as the centripetal force, but in the opposite direction. Centrifugal forces do not really exist. If you are in an accelerating frame of reference, you will see things start to move of their own accord.
What happens if the value of centripetal force is greater than the value of static friction?
If the net force is greater than static friction and in the same direction as the normal force generating the friction, the object will not move. If the force is in the opposite direction (assuming the net includes and gravitational forces) the object will accelerate upwards.
Can centripetal force and centrifugal force balance each other if not why?
NO, They do not cancel out each other, while centripetal (center seeking force) is generally provided by some other agency/force, like for revolution of planets it is provided by gravitational force, centrifugal force(outward force) is a pseudo force which is felt in the reference frame of the revolving/rotating body.
Where is the maximum centrifugal force?
the equator
Note: Centrifugal force is a force that is equal but opposite in direction to the centripetal force. These forces act on bodies that execute the circular motion. They are zero in magnitude at the poles and maximum near the equator as a result of the spinning of the earth.
Why is centrifugal force not a real force?
The centrifugal force is very real if you are in a rotating reference frame. However, the centrifugal force is an inertial force, meaning that it is caused by the motion of the frame of reference itself and not by any external force.
What’s the difference between centripetal and centrifugal force?
Centripetal force is defined as, “the force that is necessary to keep an object moving in a curved path and that is directed inward toward the center of rotation,” while centrifugal force is defined as “the apparent force that is felt by an object moving in a curved path that acts outwardly away from the center of …
Does centripetal force equal friction force?
The frictional force supplies the centripetal force and is numerically equal to it. Centripetal force is perpendicular to velocity and causes uniform circular motion.
Can centrifugal and centripetal force act simultaneously?
Yes, because it is in accordance with the Newton’s third law of motion. Pls note that thes two forces act on different objects simultaneously, i.e., e.g., on the string and on the stone. Centripetal and centrifugal forces ALWAYS act simultaneously.
How do you calculate centrifugal force?
The formula used is explained below: If you want to calculate centrifugal force you need to use: F = m * v2 / r. For mass the above formula becomes: m = F * r / v2. For radius it turns into: r = m * v2 / F. For velocity: v = square root out of (F * r / m)
What are the types of centripetal force?
In such a situation, the centripetal force is a consequence of all forces which may be present, acting collectively on the body. Often the centripetal force is the sum of several types of forces, e.g., tension, gravity, friction, normal contact forces and other forces which may be present.
What are some examples of centrifugal forces?
Some common examples of centrifugal force at work are mud flying off a tire and children feeling a force pushing them outwards while spinning on a roundabout. A major example of centripetal force is the rotation of satellites around a planet.
What is the equation for centrifugal force?
The equation for centrifugal force is Fc = mv2/r, where m equals the mass of an object, v is the speed and r is the radius, or distance from the center. Centrifugal force is defined as the outward force that an object seems to experience when it moves in a circle. Centrifugal force is felt as if it is real but does not technically exist.
