==Key Stage 5==
===Meaning===
[[Centripetal force]] is the [[Resultant Force|resultant force]] acting on an [[object]] moving in a circular path, directed towards the centre of the circle.

===About Centripetal Force===
*A '''centripetal force''' is required to keep an [[object]] in [[Circular Motion|circular motion]].
*'''Centripetal force''' can be provided by [[tension]], [[gravity]], [[friction]], or other [[force]]s depending on the situation.
*The absence of '''centripetal force''' leads to the [[object]] moving in a straight line due to [[inertia]].
'''Centripetal force''' is not a specific [[force]] but rather the result of existing [[force]]s like [[tension]] or [[Gravitational Force|gravitational force]].
'''Centripetal force''' is critical in designing structures and systems involving rotational motion, such as centrifuges, carousels and roller coasters.

===Formula===
The '''centripetal force''' acting on an object is given by the formula:

*<math>𝐹=\frac{𝑚𝑣^2}{𝑟}</math>

Where:

𝑚 is the [[mass]] of the [[object]],

𝑣 is the speed or the linear [[velocity]] of the [[object]] at a given point along the [[Circular Motion|circular path]]

and

𝑟 is the radius of the [[Circular Motion|circular path]].

===Examples===

*The tension in a string provides the centripetal force for a spinning ball on a string.
*Gravity provides the centripetal force for planets orbiting the sun.
