Question

Assertion : The position-time graph of a uniform motion
in one dimension of a body can have negative slope.
Reason: When the speed of body decreases with time.
the position-time graph of the moving body has negative
slope.​

Answer 1

Explanation:

Negative slope of position time graph represents that the body is moving towards the negative direction and if the slope of the graph decrease with time then it represents the decrease in speed i.e. retardation in motion.Sep 14, 2019
