Distance is the length covered either in a straight or curved line. And distance is the initial and final position’s distance drawn in a straight line. So, if an object starts it motion and after covering a distance in a straight or curved line, but at last finishes at its initial point then the initial and final point is one and the same thus its displacement is zero.
What is the unit of displacement?
Will distance and displacement be equal always? Explain.
What is focal distance?
