Now open this video of a man sliding across the ice. The screen shows a data table, a position against time graph, and a velocity against time graph.

Click the play button, and watch the video. Then study the position against time graph. What is the change in the motion of the man? How do you know? Is the acceleration of the man positive or negative?

Probably late but the change in motion of the man is in his speed, I know because every 0.2 seconds, he was gaining more distance as he was the previous 0.2 seconds. His acceleration positive because he was speeding up.

Explanation:

Hope it Helps!

( I realized he started off speeding up but then started slowning down so I am confused if you get this wrong Im so sorry.)

Acceleration is defined as the rate of change of the velocity of the body. The acceleration of the man is positive due to its increased velocity.

What is acceleration?

Acceleration is defined as the rate of change of the velocity of the body. Its unit is m/sec².It is a vector quantity. It requires both magnitudes as well as direction to define.

The acceleration of the man is positive because acceleration is the rate of change of velocity and the velocity of the person is increasing at an equal interval of time showing that the acceleration is increasing and positive in nature.

Hence due to successive velocity, the acceleration of the man is positive.
