Question

state the two ways of writing force equation for a circular motion

Answer 1

Answer:

Explanation:

In the case of circular motion, this force is the centripetal force. If 'm' is the mass of the body, then the centripetal force on it is given by F = mv2/r; where 'r' is the radius of the circular orbit.

Answer 2

Circular Motion

Ways of writing force equation for a circular motion are as follows:

• $Resultant \ force=-m\omega^2\vec r$
• $m\omega^2\vec r+(real\ forces)=0$

Circular motion: It  is the movement of an object along circular path. It can be uniform, non uniform with changing rotational rate etc.

In case of circular motion, the force is centripetal force, and according to Newton's second law,  it can be expressed as

$F_c=ma_c\\\\=\frac{mv^2}{r} \\\\=m\omega^2r$
