What can you say about the motion of an object whose distance time graph is
$(i)$ a straight line, parallel to the time axis ?
$(ii)$ a straight line passing through the origin making an angle with the time axis ?
When is an object in motion considered to be a point object ?
What is the numerical ratio of average velocity to average speed of an object when it is moving along a straight path ?
A particle is moving in a circular path of radius $r$. The displacement after half a circle would be :
Why is the motion of an athlete moving along the circular path an accelerated motion ?
