Answer 1

Q.1            DISTANCE:- 1. It is the total distance travelled by the body from initial to final position.

                     2. It is scalar quantity.

                     3. Distance has S.I units m/s

                     4. Distance can positive and zero.

                   Displacement:- 1. It is the shortest path between inital and final position.

                            2. It is a vector quantity.

                            3. Displacement has S.I units m/s

                            4. Displacement can be positive, negative and zero.

Q.2              Newtons third states that for every action in nature there is an equal and opposite

                    reaction.

                    In other words, if object A exerts a force on object B, then object B also exerts an equal

                    and opposite force on object A.        F₁= -F₂

Q.3              The first condition for equilibrium is that the net force on the object must be zero.
