Question

please explain about central forces​

Answer 1

Answer:

In classical mechanics, a central force on an object is a force that is directed along the line joining the object and the origin:[a][1]

{\displaystyle {\vec {F}}=\mathbf {F} (\mathbf {r} )=F(\mathbf {r} ){\hat {\mathbf {r} }}}

where {\displaystyle \scriptstyle {\vec {\text{ F }}}} is the force, F is a vector valued force function, F is a scalar valued force function, r is the position vector, ||r|| is its length, and {\displaystyle \scriptstyle {\hat {\mathbf {r} }}} = r/||r|| is the corresponding unit vector.

Not all central force fields are conservative or spherically symmetric. However, a central force is conservative if and only if it is spherically symmetric.[2]
