Jakarta –
In an object moving in a circle there are forces that are related to each other, namely the centripetal force and centrifugal force. If centripetal force is a force with a direction towards the center of the circle, then what is centrifugal force?
Simply put, centrifugal force is a force that is opposite to the centripetal force, as quoted from the Physics Module Package C SMA/MA compiled by Marga Surya (2017).
The module also states that the centrifugal force cannot be greater than the centripetal force. Why? This is because if the centrifugal force is greater, an object moving in a circle can bounce off the circular path.
Definition of Centrifugal Force
Quoted from the Journal of Centrifugal and Centripetal Forces in the Use of Sports Movements written by Iwan Arya Kusuma (2018), it is stated that centrifugal force is not real. Centrifugal force is a pseudo effect that occurs when an object moves in a circle away from the center.
The centripetal force is also known as the pseudo force or imaginary force. Even so, this force is considered to be a counterweight to the centripetal force. Even though they are in opposite directions, the magnitude of the force is the same.
If it is analogous to an event, the centripetal force works when we are riding on an earring ride or equestrian sport, bicycle racing on a circular track.
However, at that moment we feel the body is actually pushed to the outside instead of into the track. The phenomenon that we feel is the influence of the centrifugal force.
Characteristics of Centrifugal Force
From the definition and examples of centrifugal force, the following are the characteristics of centrifugal force that you need to know:
– Centrifugal is a fictitious force, has a pseudo effect, therefore it is called a pseudo force or imaginary force
– The direction of the centrifugal force is moving away from the center of the circular path
– The magnitude of the motion must be equal to the centripetal force, otherwise it can cause objects or objects to bounce off the track
– Cannot be observed with inertial frame observations
– However, by observing the non-inertial framework it can be observed
Example of Centrifugal Force
Examples of centrifugal force that are easily found in everyday life, for example, a merry-go-round in a park. Where the resulting rotating force tends to throw objects outwards.
In addition, the planet’s orbit, although we don’t see it directly, the planet revolves around the sun and maintains a motion that doesn’t approach the center or inward. In this case, the centrifugal force means that it plays an important role in maintaining the trajectory of the planet’s orbit.
Well, that’s the explanation about centrifugal force along with examples in life. Hopefully it will add insight, yes!
