to keep an object moving the way it is already moving .
so we can get the net force.
1. Whirling of a stone tied to a string: The string provides necessary centripetal force for the rotation of stone.2. Turning of vehicles in a circular track: The friction due to the tyres in case of levelled road and the angle of inclination of tracks in case of banked tracks provides the necessary centripetal force.
F=ma, or force equals the product of mass and acceleration. Assuming that the mass of the object does not change, then acceleration increases as force increases.
Newton said an object at rest will tend to stay at rest until acted upon by an external force. An object is moved when another force is applied to it. Whether it be from change in potential energy or just direct change in momentum, another force is necessary to move an object at rest.
The total input force in a given direction should be positive. (e.g. You have to overcome friction) Then by Newtons law of motion: F =ma or a =m / F which will cause a body to accelerate.
so we can get the net force.
Centripetal Force
The inward force needed for circular motion is called centripetal force. It is directed towards the center of the circle and is required to keep an object moving in a curved path instead of a straight line. Without this force, the object would continue in a straight line tangent to the circle.
Yes, in fact, it is necessary. If any net force acts on an object, the velocity will change.Yes, in fact, it is necessary.

friction increases the amount of force necessary to do work
no
It is necessary to have a strong military force with a large empire.
transferring energy to or from an object by applying a force over a distance.
Electic Force At A Distance By Jhon
the area over which the force acts
It could be called superfluous. No force is necessary to maintain motion.
Centripetal force is necessary to keep an object in a circular path.
