Firstly: Do you know what torque, angular velocity/displacement, moment of inertia is?

well what I have in mind is the use of f=ma then using and force in angular motion...how does that sound?

Why do you think you need to use force in angular motions?

Have you studied circular motion?

yeah ofcourse
Why do you think a body in circular motion is considered to be accelerating whose magnitude is calculated using a=v2/r ?

ohhh gat your point man ....well as I know there is a connection between circular and angular motion..am I right?

You should look up Newton's first and second law (especially first law) to see how they are applied to circular motion. Apparently circular and angular motion are same thing.

yeah ...btw thank you man ...i;ll try to check up on that to see if I can come up with something useful

In Newton's 2nd law of motion
Acceleration is directly proportional to Unbalanced Force
Acceleration is inversely proportional to it's Mass
F= ma

I guess for an object to be in a motion as in angular motion , we need an unbalanced force as stated by Newton's 1st law (objects don't accelerate unless an unbalanced force is applied.. if unbalanced forces = 0 , then it would move at constant velocity or be at rest ).
So unbalanced force creates the velocity as in angular motions ( or force can be used instead of velocity when speaking)
When in angular motion, the object has a vertical component and a horizontal component.
The vertical component is under W=mg (which is almost F=ma)( g=9.8 m/s^2)
So it is under Newton's 2nd law as I stated at first!

Also, the horizontal component has no acceleration.
This is why the horizontal component is the same throughout the flight.
It continues with constant velocity according to Newton's 1st law of motion as no unbalanced force acts horizontally

Hope this is the correct answer according to AS theories!
