An object experiences a net zero external unbalanced force. Is it possible for the object to be moving 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.

When an object experiences a net zero external unbalanced force, in accordance with second law of motion F = ma, its acceleration is zero. If the object was initially in a state of motion, then in accordance with the first law of motion, the object will continue to move in the same direction with same speed. It means that the object may be travelling with a non - zero velocity, but the magnitude as well as direction of velocity must remain unchanged or constant throughout.

Questions 23-25 are based on the information given below. Read the information and answer the questions that follow:A bob of mass ‘m’ is suspended by a string, g be the acceleration due to gravity the bob.When the bob is stationary, the tension ‘T’ in the string is T=mg.When the bob is pulled up with an acceleration ‘a’ the tension in the string is given by T= m (g + a)When the bob is allowed to move down with an acceleration ‘a’, the tension T in the string is given byT= m (g –a)
