The figure here shows the position of a runner at one-second intervals as he moves from left to right. Which of the following graphs will BEST represent the motion of the runner in the figure?​ (Figure is attached)

Answer:

The correct option is C.

Explanation:

• The position of the runner changes every second
• The distance travelled by the runner increases in the same amount every second
• The runner is under uniform motion
• The runner is not accelerating
• The distance covered is directly proportional to the time passed
• A straight line always appears on the line graph of uniform motion.
• Because according to the definition, uniform motion is when an object travels the same distance at the same rate of speed.
• Thus, the line is straight for uniform non-accelerated motion.

The position-time graph is thus a straight line passing through the origin (0,0).
