Analyzing Position-time Graphs

To determine how far from the detector an object is located on a Position-time graph I should...

• Look at the vertical axis at that time

• Look at the steepness of the line (slope)

• Look at if the slope is positive or negative

• Look at the direction of the curvature, if any

To determine how fast an object is moving on a Position-time graph I should...

• Look at the vertical axis at that time

• Look at the steepness of the line (slope)

• Look at if the slope is positive or negative

• Look at the direction of the curvature, if any

To determine which way an object is moving on a Position-time graph I should...

• Look at the vertical axis at that time

• Look at the steepness of the line (slope)

• Look at if the slope is positive or negative

• Look at the direction of the curvature, if any

To determine which way an object is accelerating on a Position-time graph I should...

• Look at the vertical axis at that time

• Look at the steepness of the line (slope)

• Look at if the slope is positive or negative

• Look at the direction of the curvature, if any

Describe the signs of velocity and acceleration of an object given by this Position-time graph.

• velocity = negative, accel = negative

• velocity = positive, accel = negative

• velocity = negative, accel = positive

• velocity = positive, accel = positive
