centripetal force noun. The definition of centripetal force is what allows something to move in a curved path by pulling whatever is going around in a circle into the middle of the circle. An example of centripetal force is the rotation of the Earth around the Sun.

Centripetal force A centripetal force (from Latin centrum, center and petere, to seek) is a force that makes a body follow a curved path. Its direction is always orthogonal to the motion of the body and towards the fixed point of the instantaneous center of curvature of the path. Isaac Newton described it as a force by which bodies are drawn or impelled, or in any way tend, towards a point as to a centre.

- The SI unit of force is the newton (N), which is the force required to accelerate a one kilogram mass at a rate of one meter per second squared, or kg·m·s⁻². The corresponding CGS unit is the dyne, the force required to accelerate a one gram mass by one centimeter per second squared, or g·cm·s⁻².

- The force applied on a surface in a direction perpendicular or normal to the surface is called thrust. Force, and thus thrust, is measured in the International System of Units (SI) as the newton (symbol: N), and represents the amount needed to accelerate 1 kilogram of mass at the rate of 1 metre per second squared.

centripetal force A force acting on a moving body at an angle to the direction of motion, tending to make the body follow a circular or curved path. The force of gravity acting on a satellite in orbit is an example of a centripetal force; the friction of the tires of a car making a turn similarly provides centripetal force on the car.

What Are Centrifugal & Centripetal Forces? The radius r of this circle is equal to the mass m times the square of the velocity v divided by the centripetal force F, or r = mv2/F. The force can be calculated by simply rearranging the equation, F= mv2/r. Centripetal force is the inward-seeking pull of an object. Centrifugal force is the opposite; it appears to pull objects away from the center or axis of rotation.

- force definition In physics, something that causes a change in the motion of an object. The modern definition of force (an object's mass multiplied by its acceleration) was given by Isaac Newton in Newton's laws of motion.

- The centripetal force (Fc) furnished by the weight (wt) of the suspended masses is now keeping the stopper moving in a circular path of fixed radius. It is important to keep two factors constant during the course of this exercise: the mass of the orbiting object and the radius of the orbit. The centripetal force is varied by altering the amount of mass suspended from the string. Note that the mass of the rubber stopper is 0.0045 kg and the mass of the cord is neglected.

- Diffen › Science › Physics. Centrifugal force (Latin for center fleeing) describes the tendency of an object following a curved path to fly outwards, away from the center of the curve. It's not really a force; it results from inertia — the tendency of an object to resist any change in its state of rest or motion.

Homework Help: Centripetal Force and free body diagram The problem statement, all variables and given/known data. a. Draw a free body diagram for mass Mb while in motion (fig. 2a). Identify the centripetal force. assume that the mass hangs vertically. b. Calculate the magnitude of the force exerted by the spring on mass Mb = 402g, moving in a circle of radius r=18cm (fig. 2a). The mass makes 20 revolutions in 12 seconds. Determine the mass m, suspended over the pulley (fig 2b), which stretch the spring by the same amount as during the rotation.

Definition of 'centrifugal force' Centrifugal force is what makes a propeller blade fly off if it breaks at the root.Centrifugal force is the outward force, away from the axis of rotation, acting on a revolving object.Centrifugal force is the tendency of an object moving in a circle to travel away from the center of the circle.

Centrifugal force This force is called a centripetal force because its vector changes direction to continue to point toward the center of the car's arc as the car traverses it. Now we know that the car is acting upon the passenger and therefore the passenger must be acting upon the car with an equal and opposite force.

Centripetal Force Definition of Centripetal Force. Centripetal force is a force that makes an object follow a curved path. The direction of the force is oriented at a right angle to the direction of travel of the object, toward the center of the circle along which the object is moving.

Centripetal Force The force responsible for the change in the direction of a body in turning motion is called the centripetal force and always has a direction towards the center of the circular path. The centripetal force is not an independent force in the way as forces such as weight, air resistance, etc., may be considered. In order for circular motion to be possible, some resultant force must be acting on the body with a direction always to the center of the circle. R is the radius of the circle.

Centrifugal force Centrifugal force is an outward force apparent in a rotating reference frame; it does not exist when measurements are made in an inertial frame of reference. All measurements of position and velocity must be made relative to some frame of reference.

centrifugal The definition of centrifugal is something that is moving, or that is prone to move, away from a center. A force that tends to move away from the center is an example of something that would be described as centrifugal. moving or tending to move away from a center. using or acted on by centrifugal force.

Comments: Centrifugal Force vs Centripetal Force Centripetal force is a real force that counteracts the centrifugal force and prevents the object from flying out, keeping it moving instead with a uniform speed along a circular path.

What is CENTRIPETAL FORCE? The Force that moves or rotate a body in circular path. Equal and opposite to centrifugal force; equal in magnitude to the product of the mass along with its centripetal acceleration.

What Are Centrifugal & Centripetal Forces? There are many applications that exploit centripetal force. One is to simulate the acceleration of a space launch for astronaut training. When a rocket is first launched, it is so laden with fuel and oxidizer that it can barely move. However, as it ascends, it burns fuel at a tremendous rate, continuously losing mass.
