Question

A ball is thrown vertically upwards. It rises to a height of 50 m and comes back to the thrower.
What is the displacement or distance covered by ball?

Answer 1

distance=100m
displacement=0(because it returns back to the same position)

Answer 2

Answer:

The displacement and distance covered by the ball are "0" and "100m" respectively.

Explanation:

Displacement is defined as the shortest distance or path traveled by the particle between the starting point and endpoint. Whereas distance is the measure of how much ground an object has covered during its motion.

When the ball is thrown upwards and it comes back to the thrower then,

Displacement = 0 (∴ Because the particle comes back to its starting point)

Distance=$50m+50m=100m$

Hence, the displacement and distance covered by the ball are "0" and "100m" respectively.
