What can you say about the motion of a body if its speed - time graph is a straight line
parallel to the time axis?
Can a body have constant speed but variable velocity?
Give an example of non-uniform acceleration?
Is the motion of a body uniform or accelerated if it goes around the sun with constant
speed in a circularorbit ?
