Soni says that the acceleration in an object could be zero even when several forces are acting on it. Do you agree with her? Why?
(a) Write an activity to demonstrate balanced and unbalanced forces. (b) State whether the forces are balanced or unbalanced in each case: (i) Suitcase dropped from a height. (ii) A bicycle moving with constant velocity on a straight road. (iii) The rope does not move in a tug of war on applying force at both ends.
