Question

The displacement-time graph for a ball which is thrown up, is shown below. Which among the following is the corresponding distance-time graph?

• A.
  
• B.
• C.
• D.

Answer 1

The correct option is C

A ball thrown up (under the effect of gravity) with some initial velocity possesses a combination of upwards and downwards motion.
Displacement is the shortest distance between the initial and the final points. When the object is in upwards motion, distance-time and displacement-time graphs remain the same.
However, during downward motion, the displacement starts decreasing whereas the distance keeps increasing because distance is the total path length between initial and final points.
Hence, the correct answer is option (c).
