The second law states that the rate of change if momentum is directly proportional to the force applied in the direction of force. Acceleration is Directly proportional to the bet force applied,and inversely proportional to the mass of the object. ' The greater the mass of the object the more force it'll take to accelerate the object'.

When two people push the same object but in opposite direction to each other and the applied force on both sides is same then the net force comes out to be zero, so there is no motion in the object, this is called balanced force When two people push the same object but in opposite direction to each other and the applied force is not same and the net force is not equal to zero then the object shows the motion, this is called unbalanced force
