Some examples of motion are given below.State in each case if the motion is one,two,or three dimension a)A kite flying on a windy day. b)A speeding car on a long straight highway. c)A carrom coin rebounding from the side of the board. d)A planet revolving around its star.

An external force is always required to brake the inertia of a body which is either in the state of rest or state of uniform motion. Can all forces produce acceleration? Why?
