- What does the velocity-time graph represent?
- Acceleration
- A velocity-time graph shows how an object’s velocity changes with time and helps in calculating acceleration.
- Which physical quantity is represented by the slope of a velocity-time graph?
- Acceleration
- The slope of a velocity-time graph gives acceleration, which is the rate of change of velocity.
- What does a horizontal line in a velocity-time graph indicate?
- Uniform velocity
- A straight horizontal line means that the object is moving with a constant velocity (zero acceleration).
- What does a straight sloped line in a velocity-time graph indicate?
- Uniform acceleration
- A straight sloped line means that the object is accelerating at a constant rate.
- What does the area under a velocity-time graph represent?
- Displacement
- The area enclosed by the velocity-time graph and the time axis gives the total displacement of the object.
- Which type of motion is shown by a curve in a velocity-time graph?
- Non-uniform acceleration
- A curve in the velocity-time graph indicates that acceleration is changing over time.
- What will the velocity-time graph look like for an object at rest?
- Horizontal line on x-axis
- If an object is not moving, its velocity remains zero, so the velocity-time graph is a horizontal line along the x-axis.
- What happens to velocity when the velocity-time graph has a downward slope?
- Decreases
- A downward slope in the velocity-time graph indicates that the object’s velocity is decreasing, meaning negative acceleration or deceleration.
- What is the shape of the velocity-time graph for an object moving with uniform acceleration?
- Straight line
- For uniform acceleration, the velocity-time graph is a straight line sloping upwards.
- Which physical quantity can be found using the velocity-time graph apart from acceleration?
- Distance
- The total area under the velocity-time graph gives the distance traveled by the object.
