Represent the motion of an object thrown upward with the help of velocity-time graph.

Explanation

To represent the motion of an object thrown upward with the help of a velocity-time graph, we can follow these steps:

### Step 1: Understand the Motion
When an object is thrown upward, it initially moves against the force of gravity. As it rises, its velocity decreases until it reaches the highest point, where its velocity becomes zero. After that, it starts to fall back down, and its velocity increases in the downward direction.

### Step 2: Define the Variables
- **Initial Velocity (u)**: The velocity at which the object is thrown upward.
- **Final Velocity (v)**: The velocity of the object at any time t.
