Balanced and Unbalanced Forces
Balanced and Unbalanced Forces: Overview
This topic describes balanced and unbalanced forces acting on an object. If the sum of all the forces on an object is zero, then the forces acting on it are called balanced forces. If the total force is not zero, then they are unbalanced forces.
Important Questions on Balanced and Unbalanced Forces

In the following example, try to identify the number of times the velocity of the ball changes: “A football player kicks a football to another player of his team who kicks the football towards the goal. The goalkeeper of the opposite team collects the football and kicks it towards a player of his own team”. Also, identify the agent supplying the force in each case

A batsman hits a cricket ball which then rolls on level ground. After covering a short distance, the ball comes to rest. The ball slows to a stop because
An object experiences a net zero external unbalanced force. Is it possible for the object to be travelling with a non-zero velocity? If yes, state the conditions that must be placed on the magnitude and direction of the velocity. If no, provide a reason.
