# general uniform acceleration question

#### amannaan2000

If an object is in uniform circular motion, can it be assumed that there will be no net force in the vertical direction (aka no net forces for the y component)?

$$\displaystyle \sum F_y = 0$$ if the UCM is restricted to a horizontal plane

Gyroscopes

This reads a bit like like a query regarding gyroscopes,
just approaching from a different direction.

A simple uniform circular motion, will not produce a net force perpendicular to the plane of the circle.

However if you impose a second circular motion upon your first,
in a plane perpendicular to the first,
you will find that that it produces a torque trying to rotate the system,
in the plane perpendicular to the other two.
