Transcribed Image Text:**Question:**
A ball is thrown upwards as shown in the figure. Is the work done by gravity on the ball positive, negative, zero, or undefined?
**Diagram Explanation:**
The diagram illustrates a ball being thrown upward with the following elements:
- **\(\vec{d}\):** A blue arrow pointing upwards, indicating the displacement direction of the ball.
- **\(\vec{v}_0\):** A green arrow pointing upwards from the black ball, representing the initial velocity.
- **\(\vec{v}\):** A green arrow pointing upwards from the grey ball, representing the velocity at a later moment.
- **\(\vec{F}_{\text{grav}}\):** A red arrow pointing downwards from both the black and grey balls, representing the gravitational force acting on the ball.
**Answer Choices:**
- Negative
- Undefined
- Zero
- Positive
The correct answer is indicated as "0".
