Solution

The correct option is A True

Velocity-time graph:

The slope of a velocity graph represents the object's acceleration. As a result, the value of the slope at any given time indicates the object's acceleration.

Graph:

What is the velocity - time graph of a body thrown vertically up? - Quora
  1. Because the ball was shot vertically up and subsequently down, it was subjected to gravitational acceleration or continual acceleration.
  2. As a result of the constant acceleration, the graph will be a straight line with a slope equal to the gravitational acceleration.
  3. When the ball goes upward against the gravity of the earth, its velocity will decrease uniformly.
  4. When the ball reaches a maximum height its velocity will be zero.
  5. During the fall, Ball experiences acceleration due to gravity.
  6. Due to the gravity of the earth, the free-falling ball's velocity will increase uniformly due to acceleration due to gravity.

Hence, the above statement is true.
