I think you should check the first and last answers..

The graph for ax cannot be F. Acceleration is the slope of the velocity curve. At no point does the slope of the velocity curve change abruptly.

The graph for the position x cannot be I. At t=7 the slope of the position graph I is negative so the velocity should be negative.

Related to Position and acceleration graphs

1. What is a position graph and how is it used?

A position graph shows the position of an object over time. It is often used to track the motion of an object and can provide information about its speed and direction of movement.

2. How is acceleration represented on a graph?

Acceleration is represented as the slope of a line on an acceleration graph. The steeper the slope, the greater the acceleration.

3. How do you calculate acceleration from a position graph?

Acceleration can be calculated by finding the slope of the line on a position graph. This can be done by dividing the change in velocity by the change in time.

4. Can a position graph show negative acceleration?

Yes, a position graph can show negative acceleration. This would be represented by a downward sloping line, indicating that the object is slowing down.

5. How do you interpret a curved line on a position graph?

A curved line on a position graph indicates that the object is undergoing acceleration. The steeper the curve, the greater the acceleration. The direction of the curve can also indicate the direction of acceleration.
