    What would you like the diagram to show? This diagram is a basic illustration of circular motion:



    The centripetal force is directed towards the centre of the circle and there are no other forces. This produces an acceleration towards the centre of the circle.

    On a banked track it is a combination of weight (and reaction force) and friction that produces this force. Depending on the speed, friction may act in the opposite direction but there will be a resultant force directed towards the centre if the particle is moving in a circle.
    thank you. I think that I understand

    Great, it's not an easy concept when you're used to horizontal/vertical motion in M1/M2. Just remember that for motion in a circle, there is a resultant force towards the centre (imbalanced forces) and forces are balanced in the direction perpendicular to this.

    yeah, M1 and M2 were pretty straightforward and even the beginning of M3 was fine, but this is completely alien to me.

    vertically: mg and Fr vertical are opposite to the vertical component of R. I get that.

    are the vertical forces the balanced forces youre talking about?

    Yes for circular motion vertical forces are balanced and horizontal forces are unbalanced with a resultant force directed towards the centre.

    theyre unbalanced due to acceleration?

    Yes. Or you could say there’s acceleration so they must be unbalanced
