State the effect of force F in each of the following diagrams (a) and (b).

(i) In figure (a), when a force F is applied on the ball, the ball starts moving in a straight line in the direction of force F and continues to move in that direction. This is called linear motion.

(ii) In figure (b), when a force F is applied on the wheel pivoted at a point, the force turns the wheel in anticlockwise direction about the axis of rotation producing turning motion.
