Centrifugal Force and Centripetal Force and Formulas

Centrifugal force is the force of circular motion moving away from the center of the circle and its value is positive. The centrifugal force is the opposite of the centrapetal force, which is closer to the center of the circle. Centrifugal force can be seen in centrifugal pumps, called centrifugal pumps because the force or direction of rotation of the blades is centrifugal.

Centrifugal force

A small example is when spinning a rope tied to a rock or object and then the pendulum is swung around to form a circle, the force caused by the stone, namely centrifugal force or when dancing with a partner and then making a circular motion, it is called a force centrifugal.

The magnitude of the centrifugal force is generally

Fs = m as

as = v2 / r or = 4 r3 thenFs = m v2 / r

Formula explanation

m= mass
v= centrifugal speed
r= radius

To be able to understand the centrifugal force must be able to determine the triangle of velocity. As in the image of the speed triangle below.

The reason for the absence of centrifugal force

If there is a centrifugal force acting on an object that is in circular motion, then Newton's 1st law is violated. According to Newton's first law, if there is a net force on an object, the object is either at rest or moving at a constant speed along a straight line.

When an object is moving in a circular motion, it exerts a centripetal force which is directed towards the center of the circle. If there is a centrifugal force that is directed away from the center, then there is a net force that causes the object to move along a straight line. The fact that happens, objects do circular motion. That way it can be concluded that there is no centrifugal force.

Centripetal Style

Centripetal force is the force that makes objects move in a circle.

An object can move in a circle because the object being rotated has an acceleration towards the center of the circle. This acceleration is also known as centripetal acceleration.

The centripetal force can be observed if we use an inertial reference frame, that is, a frame of reference that is at rest or moving at a constant speed to the earth. For example, when you see an object spinning. For example, if a ball is tied to the end of a string and then rotated horizontally, the centripetal force is able to keep the ball pulled towards the center until it moves in a circle. The centripetal force is the force from the tension in the string attached to the ball.

A force that causes motion in a curved path is called a centripetal force. Uniform circular motion is an example of centripetal force. This can be seen in the moon's orbit around the earth, the tension in a rope in a ball game, or a roller coaster.

Centripetal Force On Rope

The equation for the centripetal force is as follows:

Fs = mv2 / r

Description of the formula:

Fsis the centripetal force,
mis mass,
vis speed,
ris the radius of the path of motion.

Looking back at the atom in Newton's Second Law (Acceleration), we can see that the centripetal acceleration is:

as = v2/r.

The style equation is: F = m. a.

From this, it can be seen that the equation for the centripetal force is

Fs = mv2 / r

Formula description:

Fsis the centripetal force
mis mass,
vis speed,
ris the radius of the path of motion.

The centripetal force can also be expressed in terms of angular velocity. The angular velocity which is a measure of how fast an object crosses a circular path. As a traveling object, it sweeps an arc that can be measured in degrees or radians. The equation for the centripetal force using the angular velocity is:

Fs = mrω2

formula explanation:

Fsis the centripetal force
mis mass,
ωis the angular velocity
ris the radius of the path of motion
