A body thrown in the vertically upward direction rises
upto a height 'h' and comes back to the position of its start.
Calculate the total distance travelled by the body and
the displacement?
Answers
Answer:
total distance is 2h,due to upward and downward motion.
displacement is zero., since the ball arrived the same point from where it starts.
Given that, a body is thrown in the vertically upward direction which is rises upto a height 'h' and comes back of start.
[ Refer the attachment for figure. ]
Assume that a body is thrown upward from a point A to B. When it reaches to point B it returns back to its actual position i.e. point A.
We have to find the distance travelled by the body and displacement of the body.
Case 1) [ For Distance ]
Since, it starts from point A and reaches at point B, at that time distance travelled by the body is 'h' (as given in question) then it returns back to point A. Here, again distance travelled by the body is 'h'. So, total distance travelled by the body is h+h i.e. 2h.
Case 2) [ For Displacement ]
Displacement is defined as the shortest path between the initial and final points. Starting point of the body is A and then reaches at point B and then again at point A. So, final point is B. As starting and final points are same. So, displacement of the body is h-h i.e. zero.
