Description : Centripetal force is the force acting on an object in
|
||
curvilinear motion directed towards the axis of rotation
|
||
or centre of curvature.
|
||
|
||
The unit of centripetal force is newton.
|
||
|
||
The centripetal force is always directed perpendicular to the
|
||
direction of the object’s displacement. Using Newton’s second
|
||
law of motion, it is found that the centripetal force of an object
|
||
moving in a circular path always acts towards the centre of the circle.
|
||
The Centripetal Force Formula is given as the product of mass (in kg)
|
||
and tangential velocity (in meters per second) squared, divided by the
|
||
radius (in meters) that implies that on doubling the tangential velocity,
|
||
the centripetal force will be quadrupled. Mathematically it is written as:
|
||
F = mv²/r
|
||
Where, F is the Centripetal force, m is the mass of the object, v is the
|
||
speed or velocity of the object and r is the radius.
