Answer 1

1. for first i think it should be displacement as others are like measures of its speed and think displacement is like the path kr distance 2.girl swinging on a swing i think its more of sense here others will react to gravity will be pulled downwards and will stop sometime but for her its her choice 3.motion of a electric drill bcz others are examples of circular motion while it is of rotational motion . . . ....................................Plz correct me if i m wrong
