Even when an object experiences a net zero external unbalanced force, it is possible that the object is travelling with a non-zero velocity. This is possible only when the object has been moving with a constant velocity in a particular direction. Then, there is no net unbalanced force applied on the body. The object will keep moving with a non-zero velocity. To change the state of motion, a net non-zero external unbalanced force must be applied on the object. Inertia of an object tends to resist any change in its state of rest or state of motion. When a carpet is beaten with a stick, then the carpet comes to motion.

The frictional force exerted by fluids is also called drag or fluid friction. To overcome or minimize air fluid friction, the bodies of objects minimise its surface i.e. sometime spherical shapes or other streamlined shape with smooth surface. Aeroplanes, jets, rain drops have streamlined curve surface to reduce air drag. Friction is both a friend and a foe due to following reasons: Friction act as friend: We are able to walk because of frictional forces between ground and our feet. We are able to write because of friction between ball point and the paper surface. Nails and screws stick to wall surfaces because of friction. Lighting a match stick is because of friction between match stick and the side surface of match box. Friction act as foe: Wear and tear of soles of our shoes is due to friction. When a tyre deflates, it is difficult to move the vehicle because of increased friction between the tyre and road surface. Machines gets heated up because of friction. Due to friction, machines and vehicles consumes more fuel and increase maintenance cost. Class 8 Science Chapter 9 MCQ with Answers 1.
