Q. Assertion In realistic situation, the $x-t, v-t$ and $a-t$ graphs will be smooth.
Reason Physically acceleration and velocity cannot change values abruptly at an instant.

Motion in a Straight Line

Solution:

The $x-t, v-t$ and $a-t$ graphs will be smooth, which means that physically, the values of acceleration and velocity cannot change abruptly as changes are always continuous. Therefore, Assertion and Reason are correct and Reason is the correct explanation of Assertion.
