The one that's perfectly vertical (parallel to the y-axis).
A vertical line segment on a velocity versus time graph represents an instantaneous change in velocity, which is physically impossible. It would mean that an object goes from one velocity to another instantly, without any acceleration. In reality, objects need time to change their velocity due to the presence of acceleration or deceleration.
Assuming position is on the y axis and time is on the x axis, a positive slope means the position has increased over time.
In a position versus time graph, time is typically considered the independent variable because it is controlled by the experimenter and is used to measure the dependent variable, which is position. The position of an object (dependent variable) changes over time (independent variable), and thus position is plotted against time to show how it varies based on the passage of time.
The position versus time graph of a body undergoing constant acceleration is a curved line that slopes upwards or downwards, depending on the direction of acceleration. The curve is not a straight line because the velocity of the body is changing at a constant rate.
If a line on a distance versus time graph is horizontal, it indicates that the object is not changing its position over time. In other words, the object is at rest and not moving.

A physically impossible line segment on a position versus time graph would be one with a slope representing a speed greater than the speed of light or negative speed (moving backwards in time). These scenarios violate the laws of physics.
A vertical line segment on a velocity versus time graph represents an instantaneous change in velocity, which is physically impossible. It would mean that an object goes from one velocity to another instantly, without any acceleration. In reality, objects need time to change their velocity due to the presence of acceleration or deceleration.
A physically impossible line segment on a velocity vs. time graph would be one with a horizontal slope, indicating constant acceleration. This would violate the laws of physics, as constant acceleration requires a non-zero force. Similarly, a vertical line segment would represent an instantaneous change in velocity, which is also physically impossible as it would require infinite acceleration.
Mission Impossible Versus the Mob - 1969 is rated/received certificates of: Norway:16 (1969) UK:A (cut)
The position versus time graph is parabolic.
instantaneous magnitude of velocity
Chuck - 2007 Chuck Versus the Seduction Impossible 4-14 is rated/received certificates of: Brazil:10 USA:TV-PG
If a position versus time graph is parabolic, then:Speed versus time is a straight line.Acceleration (magnitude) vs time is a horizontal line, so the acceleration is constant.The graph of height/time for a stone or a baseballtossed upward is an inverted parabola.
The slope of the curve.
Assuming position is on the y axis and time is on the x axis, a positive slope means the position has increased over time.
