What will be the velocity v/s time graph of a ball falling from a height before hitting the ground look like?

(a) A straight line with positive slope

(b) A straight line with negative slope

(c) A straight line with zero slope

(d) A parabola

This question was posed to me during an interview for a job.

Enquiry is from Straight Line Motion in chapter Motion in a Straight Line of Physics – Class 11

Best answer
Right option is (a) A straight line with positive slope

The best I can explain: As the ball falls down, its velocity increases. This is because of the acceleration due to gravity. Hence the graph looks like a straight line with positive slope. The first equation of motion verifies this.
