F=mac=mv /r
Where,
F is the Centripetal force.
ac is the Centripetal acceleration.
m is the mass of the object.
v is the speed or velocity of the object.
r is the radius.
The unit of centripetal force is Newton. The centripetal force is always directed
perpendicular to the direction of the displacement of the object.
If an object accelerates according to the changes of velocity, then it can change either
its speed or direction of motion. In simple terms, if any moving object in a circular path is
constantly changing its direction means it is constantly accelerating. Using Newton’s
second law of motion if an object is travelling in a circular path, it is found that the
centripetal force of an object moving in a circular path always acts towards the centre of
the circle.
Centripetal Force Examples
The force that pulls or pushes an object toward the centre of a circle as it travels;
causing angular or circular motion is called a Centripetal Force. Some examples of
Centripetal Force are given below.
