प्रश्न
Read each statement below carefully, and state, with reasons, if it is true or false;
During rolling, the force of friction acts in the same direction as the direction of motion of the CM of the body
उत्तर
False
The frictional force acts opposite to the direction of motion of the centre of mass of a body. In the case of rolling, the direction of motion of the centre of mass is backward. Hence, the frictional force acts in the forward direction.

The instantaneous acceleration of the point of contact during rolling is zero.
A fat person is standing on a light plank floating on a calm lake. The person walks from one end to the other on the plank. His friend sitting on the shore watches him and finds that the person hardly moves any distance because the plank moves backward about the same distance as the person moves on the plank. Explain.
To accelerate a car we ignite petrol in the engine of the car. Since only an external force can accelerate the centre of mass, is it proper to say that "the force generated by the engine accelerates the car"?
